About Social Media Image Sizes
Social Media Image Sizes handles a focused step in the modern web and productivity utility workflow. Complete reference of optimal image sizes for Instagram, Twitter, Facebook, LinkedIn, YouTube, TikTok, and Pinterest. The page loads with the upload area, controls and result panel all visible at once, so the path from "I have a file" to "I have the result" is one screen long.
Social Media Image Sizes runs on standard browser APIs — an open-source, well-audited engine that performs the web and productivity utility natively in the browser. It accepts the formats listed in the upload area and produces output that opens in any standard web utility viewer. Per-run input is capped at 0 MB.
Common audiences for Social Media Image Sizes include creators experimenting with formats and marketers running campaigns, but plenty of people land on the page through a one-off search and never come back — that is also fine. The tool is built to be useful even when you only ever need it once.
Social Media Image Sizes is structured so the question "where is my file processed?" has a single answer: in your browser tab. The engine, the controls, and the result panel are all on one page. Navigating away or closing the tab clears the page's memory the way it does for every other tab.
The right moment to reach for Social Media Image Sizes is when you have a focused web and productivity utility job that fits inside a browser tab. Open the page, drop in the file or paste your input, choose the options that matter, and the tool returns the result.
When the job finishes, Social Media Image Sizes 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.
The hard constraints are easy to remember. Maximum input: 0 MB. Multiple files per run: no — one input at a time, by design, to keep results predictable. The same controls apply on every run.
If your task needs more than one step, chain Social Media Image Sizes with Social Media Audit Checklist, Social Media Planner, and Social Media Character Counter. Each tool produces output that is a clean input to the next, so multi-step workflows are just a matter of opening the next tool in a new tab and continuing.
Social Media Image Sizes 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.
Social Media Image Sizes 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.
Social Media Image Sizes is built around the moment of need: a focused page you open when you have a specific task, complete the task, and close. The catalog contains many adjacent tools so the same model serves the surrounding parts of a typical web and productivity utility workflow.
If you want to get the most out of Social Media Image Sizes, 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.
For most failure modes, refreshing the page and re-running the job is enough — the engine has no persistent state to corrupt. If the same input fails twice in a row, the input itself is most likely the problem (a truncated file, an unexpected variant of the format, or a stream the engine does not recognise).
That is the whole tool. Use Social Media Image Sizes for as long as it stays useful to you, and if it does, the catalog has many more tools built the same way. Each applies the same single-purpose discipline, so the way you used this page transfers to the next one you try.

FAQ
Are these sizes up to date?
Sizes reflect current platform recommendations. Platforms may update specifications periodically.
What about retina displays?
The listed sizes work for all displays. For retina optimization, use 2× dimensions.
File format?
JPEG for photos, PNG for graphics with transparency, WebP for smaller file sizes where supported.
Maximum file size?
Varies by platform — typically 8-30 MB for images and 150 MB-4 GB for videos.
Aspect ratio importance?
Critical — wrong aspect ratios cause cropping. The listed ratios ensure your content displays fully.
Private?
Yes — reference generated locally.
Will Social Media Image Sizes ask me to pay to download the result?
Social Media Image Sizes is free to use. The processing runs in your browser, which keeps the per-user cost low enough that the tool can be offered openly. The download is the same file the engine produced — you can use it for as many runs as you need.
What should I do if Social Media Image Sizes fails on my file?
Failures usually fall into one of three buckets: the input is in an unsupported format, the input is over the size cap, or the input is structurally malformed (a truncated download, a partial export, or a stream the engine does not recognise). The first two are easy to confirm — check that your file is in a supported format and that it is below 0 MB. For the third, opening the file in its native viewer first is the fastest way to confirm the source is intact.
Will Social Media Image Sizes keep working in a year?
Social Media Image Sizes is updated whenever the underlying engine releases an improvement or a bug fix. Because the tool is delivered as a static page, every visit fetches the latest version automatically — there is no "version" to manage on your end. If a particular release ever changes default behaviour, the change is documented on Favtoo's changelog so you can confirm what shifted.
Does Social Media Image Sizes ask for any browser permissions?
Social Media Image Sizes 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 Social Media Image Sizes work with screen readers?
Social Media Image Sizes 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.
Why use Social Media Image Sizes instead of a paid online tool?
Desktop apps usually have more advanced features but require installation, maintenance and (often) a licence. Paid online tools are convenient but route your file through their servers and gate downloads behind accounts. Social Media Image Sizes sits in between: free, instant, and private, but intentionally narrow in scope. For one-off jobs and the common web and productivity utility operations, it is usually the lowest-friction choice; for highly specialised work, a dedicated app is still the right answer.
Are jobs run with Social Media Image Sizes stored anywhere?
Favtoo keeps no copy of your file because Favtoo never receives your file. Social Media Image Sizes runs entirely in your browser, the input is held only in your tab's memory, and closing the tab discards it. There is no opt-in cloud history, no "recent jobs" panel synced to an account, and no server-side retention to configure — the architecture simply has nowhere for your file to be stored.
Is Social Media Image Sizes licensed for business use?
Social Media Image Sizes 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.
