imageAbout Image Splitter
Image Splitter is shaped around how people actually use image editing and conversion utilities online: open the page, drop in a file, get the result. Upload an image and split it into a grid of tiles with configurable rows, columns, and gap size. The interface stays out of the way once the work begins so the engine can use the available CPU and memory for the actual transformation.
Image Splitter fits naturally into the workflow of social-media managers sizing posts and e-commerce owners cleaning product shots, both of whom typically need a fast result inside the browser. There is no learning curve to budget for: anyone who has used a typical web upload form can complete a run on the first try.
Image Splitter is shaped for the gap between "I'll do it by hand" and "I'll script it." When the job is small enough that automating it would take longer than doing it, but annoying enough to want a focused tool — that is the situation this page is built for.
Image Splitter runs on standard browser APIs — an open-source, well-audited engine that performs the image editing and conversion natively in the browser. It accepts PNG, JPG, GIF, WebP, BMP, and SVG and produces output that opens in any standard image viewer. Per-run input is capped at 100 MB.
Because everything runs in the page, the tool scales the same way for one user or a million — there is no per-user backend cost. The page is static, the engine is the same JavaScript bundle for every visitor, and the work happens on the visitor's own device. That keeps the tool free and keeps it fast on the first interaction.
Image Splitter sits in a small group of related tools. Useful neighbours include Photo Grid Maker, Collage Maker, Sprite Sheet Generator, and Image Compare Tool. They are designed to compose: the output of one is a sensible input to the next, so a multi-step task is usually a sequence of single-click operations.
The only practical limit is the 100 MB per-file ceiling, which keeps the tool responsive across a wide range of devices. Run the tool ten times in a row, run it ten thousand times — it behaves the same way and produces the same quality of result.
Image Splitter 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.
When the job finishes, Image Splitter hands you the result as a sensibly named file. Filenames are derived from your input where possible, so a quick batch of jobs leaves you with a tidy folder rather than a pile of generic "output (3)" files. Nothing is auto-saved on Favtoo's side because nothing was ever sent there.
Image Splitter is one example of a broader pattern: utility software increasingly works as single-page, client-side experiences. Every page in the catalog is shaped that way, which keeps each tool fast to load and easy to recommend in a single link.
Image Splitter fits the gap where opening a desktop app feels heavy and writing a script feels overkill. The page handles the common image editing and conversion task with sensible defaults so a single visit usually completes the job; for highly specialised work, a dedicated desktop application can offer more knobs to turn.
Tips from users who reach for Image Splitter regularly: process one input first to confirm the settings produce what you expect before committing to a batch; treat the page as the working surface and avoid leaving large jobs running in a backgrounded tab where the browser may throttle JavaScript; and if a particular file fails, check whether the source is intact by opening it in its native viewer — most "tool errors" are actually input errors.
When something goes wrong, the cause is usually one of three things: a malformed input, a browser that is out of memory, or a corporate proxy that is interfering with the page's static assets. The first two are easy to diagnose; the third typically requires asking your IT team to allow standard browser APIs to load.
If Image Splitter solved your problem, sharing the page link with someone who has the same problem is the most useful thing you can do. The catalog grows mostly through word of mouth; visitors arriving through a recommendation tend to be the ones the tool serves best.
How it works
- 1Open Image Splitter in your browser. The page loads quickly and the tool is ready to use the moment it becomes interactive.
- 2Drop a PNG, JPG, GIF, WebP, BMP, and SVG file onto the upload area, or click to pick one from your device.
- 3Pick any non-default settings you need. Most users leave the defaults alone for the first run and only revisit if the result needs tuning.
- 4Trigger processing. standard browser APIs reads your input, applies the transformation, and writes the result back into the page.
- 5Grab the output as soon as the run completes. You can also copy the result instead of downloading if the next tool in your workflow accepts pasted input.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.

Set to 3×3 for standard Instagram grid posts.
Output format?
Choose PNG (lossless) or JPEG for the individual tiles.
Is my data safe?
Everything runs in your browser — nothing is uploaded.
Naming convention?
Tiles are numbered sequentially from top-left to bottom-right.
Uneven splits?
Images that do not divide evenly will have slightly trimmed edge tiles.
Is Image Splitter licensed for business use?
Image Splitter 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.
Why does Image Splitter feel slow on large inputs?
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 100 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
Can I trust the output of Image Splitter for important work?
Image Splitter 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.
Can I call Image Splitter from a script?
Image Splitter is a browser-only tool by design and does not expose a hosted API. The reason is the same as the privacy story: there is no Favtoo backend doing the work, so there is no service to call. If you need to script the same transformation, the underlying engine (standard browser APIs) is open-source and can be used directly from your own code.
Why is my browser prompting me when I open Image Splitter?
Image Splitter 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.
What input formats are supported by Image Splitter?
Image Splitter accepts PNG, JPG, GIF, WebP, BMP, and SVG. If your input is in a format that is not directly supported, convert it first using one of Favtoo's converter tools — every Favtoo converter outputs a file that is a clean input to the next tool in the chain.
Are there any usage limits on Image Splitter?
Inputs are capped at 100 MB per file, which keeps memory usage stable across phones, tablets and older laptops. You can run Image Splitter as often as you need; every run produces a full-quality result.
Is it safe to use Image Splitter on confidential files?
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 self-host Image Splitter for my team?
Image Splitter is a static page running an open-source engine in your browser, so a typical corporate firewall does not get in the way as long as it allows JavaScript to load from Favtoo. For teams that need to host it themselves on an internal network, the underlying engine (standard browser APIs) is open-source and can be packaged into a private build with the same behaviour. Reach out via the Contact page if that is something you are exploring.
