GIF Frame Viewer
Load a GIF to read its dimensions, aspect ratio, and file size and see its first frame drawn as a still.
Images never leave your browser.
Runs in your browser. Nothing you enter is uploaded.
What it does
This viewer is a quick inspection tool for animated GIFs (it also accepts still images). It reports width, height, simplified aspect ratio, file size, and file type, and draws the first frame onto a canvas so you can see what shows before the animation starts or when autoplay is off.
Be clear about the limit: browsers do not expose individual GIF frames to a canvas, so this page shows the first frame only and does not count or step through frames. For checking whether a GIF fits a size limit or the right shape for a post, it gives you the numbers you need.
How to use it
- 1
Click Choose a GIF or image and select the file.
- 2
Read Width, Height, Aspect ratio, File size, Type, and Frames in the stats grid.
- 3
Look at the First frame preview to see the opening still.
- 4
If the file is too heavy, resize or compress the source before posting.
What you get
A stats grid (width, height, aspect ratio, file size in KB, MIME type, and a Frames value of "1 (preview)" for GIFs) plus the first frame drawn on a canvas.
When to use it
- Check a GIF against upload limits
- Read the file size in KB before uploading to a platform or email tool that caps GIF size.
- Preview the poster frame
- See the first frame on its own, which is what many email clients and paused players show.
- Confirm the GIF shape
- Check whether a reaction GIF is square, 16:9, or something odd before placing it in a layout.
Tips
- The first frame is what some email clients show, so make sure it makes sense on its own.
- GIF file size grows with both dimensions and frame count; shrinking the width is usually the fastest way to get under a limit.
- Use a desktop GIF editor if you need to export or count individual frames.
Questions
Why does the GIF frame viewer only show one frame?
When a browser draws an animated GIF onto a canvas it provides a single frame, and full frame extraction needs a dedicated decoder library that this tool does not use. Dimensions and file size are still accurate.
Can I download frames from my GIF as images?
No. There is no export button. You can right-click the first frame preview in most browsers to save it, but other frames are not available here.
Does the viewer tell me how many frames my GIF has?
No. The Frames field shows "1 (preview)" because the browser does not report the real frame count to the page.
Can I inspect an animated WebP or APNG here?
You can load them, and dimensions and file size are reported, but they are handled as ordinary images with a single preview frame.
