EXIF Data Editor — Edit Image Metadata
Configure EXIF metadata fields like title, author, copyright, and description for image files.
About EXIF Data Editor
Configure EXIF metadata fields like title, author, copyright, and description for image files.
EXIF editing happens entirely inside your browser using piexifjs. Pixel data is left untouched — only the small EXIF block in the JPEG header is rewritten. Your file is never uploaded.
Editing is currently limited to JPEG because EXIF is JPEG-native; PNG and WebP use different metadata standards. To edit metadata in those formats, convert to JPEG first or use the Image Metadata Editor for IPTC/XMP fields.

About EXIF Data Editor
EXIF Data Editor is an image tool that runs in your browser. Configure EXIF metadata fields like title, author, copyright, and description for image files. The page you are reading is the same workspace you will use to do the work: pick a file or paste your input, choose the options that matter to you, and the tool produces the result on your device.
Most people land on EXIF Data Editor via a search at the moment they actually need the tool. That shapes the design: the page is a single screen with the input on one side, the controls in the middle, and the result on the other, so a first-time visitor can complete the job without reading documentation.
EXIF Data Editor parses your file with standard browser APIs entirely inside the browser, applies the options you selected, and returns a download. The processing has no network step, which means a slow or intermittent connection does not slow down the work — once the page is loaded, only your CPU and RAM are involved.
Technically, the work is done by standard browser APIs, loaded as part of the page. Inputs are recognised automatically and validated before the engine begins processing. Files up to 0 MB are supported per run; that ceiling keeps browser memory usage stable on a wide range of devices.
The 0 MB ceiling on input size is the only fixed limit. Output files are produced in standard formats that every common viewer recognises, and the tool runs the same way regardless of how many times you have used it during the session.
The heaviest users of EXIF Data Editor tend to be bloggers preparing hero images, photographers exporting deliverables and students compiling visual reports. Each group brings slightly different expectations to the tool, but the same single-page architecture serves every one of them with the same response time.
EXIF Data Editor returns the result as a download. If you are running multiple jobs, the output names will not collide as long as the input names differ. You can re-run with different settings as many times as you like; each run produces a fresh file with no caching trickery in between.
EXIF Data Editor fits naturally next to several adjacent tools. Common companions include EXIF Data Viewer, EXIF Data Remover, Image Metadata Editor, and Image Metadata Viewer — combine them when the job needs more than one transformation. After running EXIF Data Editor, many users move on to EXIF Data Viewer and EXIF Data Remover. Each tool is a separate page so you can compose the exact pipeline you need.
EXIF Data Editor keeps the control set focused. Every option on the page is there because a real workflow needs it, and the defaults aim at the most common case so a first-time user can get the right output without changing any settings.
Some background on the design choices behind EXIF Data Editor: every option you see on the page is there because a real workflow needs it, and every option that is not shown has been deliberately omitted to keep the common case fast. The bias is toward minimal-but-complete.
As a single-page tool, EXIF Data Editor stays focused on one image editing and conversion step. Multi-step workflows are composed by chaining adjacent tools — each tool produces a standard file the next one can read directly, so a longer pipeline is just a sequence of short tab-and-tab visits.
If you want to get the most out of EXIF Data Editor, three small habits help. Drag-and-drop is faster than the file picker once you get used to it. The keyboard shortcut for downloading the result is whatever your browser uses for "save link as," because the result is a normal download. And if you are working on a sensitive file, processing in an Incognito or Private window is a good extra layer — it leaves no trace in browser history when the tab closes.
If the result is not what you expected, the most common causes are easy to check. Confirm the input is under the 0 MB ceiling — files just above the cap fail silently because the engine refuses to allocate the buffer. Confirm the input is one of the supported formats. And if the page itself feels slow, try closing other heavy tabs to free up memory; the engine runs in your browser, so it competes for the same resources as everything else open.
EXIF Data Editor is one of many single-purpose tools in the catalog. Each is built around the same single-page model. Use this one, close the tab, and come back the next time you need the same job done. None of the tools require prior knowledge of the others — each page is self-contained.
How it works
- 1Open the EXIF Data Editor workspace above. The interface is a single page, so there is nothing to navigate.
- 2Drop a image file onto the upload area, or click to pick one from your device.
- 3Tweak the controls if the defaults are not quite right for your input. The options are kept short and labelled in plain language.
- 4Hit the run button. standard browser APIs does the work in your browser tab.
- 5Save the output when it is ready.
- 6Run additional jobs as needed. The same controls and defaults apply on every run.
Common use cases
- Strip EXIF data from a photo before posting it publicly using EXIF Data Editor.

- Generate a square thumbnail from a wide marketing photo.
- Apply a quick filter for a social-media post.
- Sharpen a slightly soft photo before sending it to print.
- Produce a printable poster from a single source image.
- Crop an image down to the section you actually want to share.
- Compose a mockup banner without bouncing between three different apps.
- Optimise a product photo so it loads quickly on a slow connection.
FAQ
Which metadata fields can I edit?
Title, artist/author, copyright notice, image description, and software signature — the five string tags inside the IFD0 block that desktop apps (a professional photo editor, a desktop image editor, Preview, Windows Explorer) all read consistently. The editor pre-fills any existing values it finds so you can edit one tag without erasing the others.
Does editing change pixel data?
No. The JPEG container is parsed with piexifjs, the EXIF segment is rebuilt with your new values, and the rest of the file (every byte of the compressed image data) is written back unchanged. Output quality is byte-for-byte identical to the input.
Why JPEG only?
JPEG is the only common camera/phone format that stores its EXIF in a fixed APP1 marker that can be safely re-written without re-encoding pixels. PNG/WebP/HEIC need a full pixel re-encode to change tags, which would defeat the point of a lossless metadata edit. Use the Image Metadata Editor for cross-format viewing.
Can I remove GPS coordinates here?
For removing tags wholesale, use the EXIF Data Remover, which has explicit toggles to drop the GPS IFD, the Interop IFD, and embedded thumbnails. The editor is intended for setting attributions, not stripping personal data.
Where do these fields show up?
Title and description appear under "Subject" and "Comments" in Windows file properties, "Description" in macOS Preview, and the "Title"/"Caption" fields in a professional photo editor and Photo Mechanic. Copyright shows as "Author" / "Copyright" in most viewers.
Why is in-browser metadata processing slower than online tools?
Server-side editors run native binaries (ExifTool, libexif) compiled to machine code on dedicated hardware. Our engine uses exifr for parsing and piexifjs for editing, both pure JavaScript libraries running single-threaded inside your browser tab. That's typically 2–5× slower than a backend pipeline. The trade-off is total privacy: your image and its embedded GPS coordinates, camera serials, and other personal metadata never leave your device. The whole point of metadata tools is privacy, and a few extra milliseconds is a fair price to pay for keeping that data on your machine.
Is my image uploaded to a server?
No. exifr parses the file header in your browser memory, and piexifjs writes any changes locally. The processed file is offered as a direct download. Nothing is transmitted, no account is required, and closing the tab discards every byte from memory immediately.
Which image formats are supported?
Reading metadata works on JPEG, PNG, WebP, AVIF, HEIC, TIFF, GIF, and most other formats exifr supports. Editing and removing EXIF tags is fully supported on JPEG (the most common camera format). For PNG/WebP/etc., the remover re-encodes the image through canvas, which strips all embedded metadata as a side effect.
Which metadata fields can I see or edit?
Viewing surfaces all standard EXIF tags (camera make/model, lens, aperture, ISO, shutter speed, focal length), GPS coordinates, IPTC photo metadata (title, caption, keywords, copyright), XMP packets, ICC colour profile info, and JFIF container fields. Editing focuses on the human-readable string tags inside the IFD0 block — title, artist, copyright, description, software — which are the fields most authoring tools respect.
Does editing or removing metadata change the pixels?
No, JPEG metadata edits are byte-level container rewrites that leave the compressed image data untouched. There is zero pixel re-encoding and zero quality loss. For non-JPEG formats the metadata remover does re-encode pixels through a canvas, which strips every embedded tag at the cost of a small re-compression pass.
Which browsers are supported?
Recent Chrome, Edge, Firefox, Safari, and other Chromium-based browsers all work. The tool only relies on standard ArrayBuffer, FileReader, and Canvas APIs that have been universally supported for over a decade.
Is there a watermark or sign-up wall?
No. The tool is completely free, requires no account, attaches no watermark, and shows no popup ads on your output. A small fair-use throttle runs in the background to discourage automated abuse, but it does not affect normal one-off use. The downloaded file is exactly what your browser produced — nothing more, nothing less.
Are there any restrictions on using EXIF Data Editor at work?
EXIF Data Editor can be used for personal and commercial work alike — there is no separate "business" licence to purchase. The output you generate is yours to use however you want, including in client deliverables, internal documents, or commercial products. Favtoo's only ask is fair, individual use; the tool is not designed to be embedded as a backend service or wrapped behind an API for resale.
Does EXIF Data Editor upload my file to a server?
Your file is processed inside your browser by standard browser APIs. The engine reads the file's bytes from your tab's memory, computes the result, and writes the result back into the tab. You can confirm what the page does by opening developer tools and watching the Network tab during a run — the requests you see are for the tool's static assets only.
Can I trust the output of EXIF Data Editor for important work?
EXIF Data Editor is built on standard browser APIs, which is the same class of engine used by professional image editing and conversion pipelines. For deterministic operations, the output is byte-identical to what an equivalent CLI run would produce; for operations involving a codec or a model, the result is well within the range of what comparable tools generate. If you have a specific reference output you need to match, run a small test job first to confirm the configuration produces what you expect.
What permissions does EXIF Data Editor need to function?
EXIF Data Editor only needs the standard web platform — file picker access for the inputs you choose to load, and optionally clipboard access if you copy the result rather than downloading it. There is no microphone, camera, geolocation or background-permission request, because none of those are needed for the work the tool does.
Does EXIF Data Editor work with screen readers?
EXIF Data Editor uses native HTML controls wherever possible, which means keyboard navigation, focus rings, and screen-reader labels work the way the platform expects. The drop zone accepts files via the keyboard-accessible file picker as well as drag-and-drop, and result downloads use standard browser download flows. If you spot an accessibility gap, Favtoo treats it as a bug worth fixing.
Will I notice a difference in the output from EXIF Data Editor?
EXIF Data Editor is built to preserve quality wherever the underlying image format allows it. Operations that are mathematically lossless (e.g. structural transformations, lossless re-encoding) round-trip with no perceptible change. Operations that involve a lossy codec inevitably introduce small artefacts at the byte level, but the defaults aim at the sweet spot where output looks or sounds the same to a normal viewer or listener while still being meaningfully smaller or faster than the input.
How fast is EXIF Data Editor?
Most jobs finish in seconds. Speed scales with input size and with how many CPU cycles your browser tab has available — the engine runs in your browser, so it shares resources with whatever else you have open. For inputs near the 0 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
