How to use Find GIF Dimensions
- 1. Upload the GIF. Drop in or browse for the animated GIF whose size you need. The tool reads the GIF's logical screen descriptor directly, so no frame decoding delay is needed for this measurement.
- 2. Read the result. The output reports the canvas width and height in pixels, for example 480 by 270 px. This is the fixed frame size every layer of the animation is drawn onto.
- 3. Copy the dimensions. Copy the result to paste into a spec sheet, an image tag's width and height attributes, or a bug report that needs the exact pixel size of the animation.
When to use Find GIF Dimensions
Find GIF Dimensions reads the width and height baked into a GIF file's header and reports it in pixels. It answers a question that is otherwise annoying to check without opening an image editor. The check runs entirely in your browser without uploading the file anywhere.
- Setting explicit image tag dimensions. Adding width and height attributes to an img tag prevents layout shift while a page loads. Reading the GIF's exact pixel size first means you set those attributes correctly.
- Checking an asset against a spec. A design brief calls for animated assets at a specific resolution, like 600 by 400. This tool confirms whether a delivered GIF actually matches that spec before it ships.
- Debugging a stretched embed. A GIF looks distorted when embedded in a CMS. Reading its true dimensions tells you whether the embed is resizing it incorrectly or the source file itself has an odd aspect ratio.

About the Find GIF Dimensions tool
Find GIF Dimensions does its work locally, right in the browser. Read the width and height of an animated GIF in pixels. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the GIF Tools collection on EditSafely, a set of 110 small, focused GIF utilities that share the same instant, private workspace.
There is nothing to configure. Provide the input and the result appears on its own. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Is Find GIF Dimensions free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Are my files uploaded to a server?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
Which files does Find GIF Dimensions accept?
It accepts GIF animations. There is no file size cap imposed by a server; very large files are limited only by your device's memory.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
