How to Resize a GIF Online
Follow these three simple steps to resize an animated GIF. No software installation required.
Add Your GIF Files
Select animated GIF files individually, choose a folder, or drag and drop them into the browser.
Choose the New Size
Resize by percentage using 25%, 50%, 75%, 100%, or a custom value, or enter an exact width and height in pixels.
Resize and Download
Start resizing, compare the original and output dimensions and file sizes, preview each animation, then download files individually or as a ZIP.
How Does the GIF Resizer Work?
The GIF resizer changes the pixel dimensions of every frame and exports the result as an animated GIF. Choose a percentage to scale the width and height together, or enter an exact width and height when a specific output size is required. GIF files can be resized individually or in bulk with the same settings. Processing runs locally in your browser, and the files are not uploaded to a server.
What "processed locally" means
- Your GIF files are not uploaded to a server
- Every animation frame is resized on your device
- The resized GIF files are downloaded directly from your browser
GIF Resize Options Explained
Choose percentage resizing for proportional scaling, or enter exact dimensions when the output must match a specific width and height.
| Resize option | What it changes | Best for |
|---|---|---|
| Percentage presets | Scales width and height together to 25%, 50%, 75%, or 100% | Quick proportional resizing |
| Custom percentage | Scales both dimensions together by a custom percentage | Precise proportional resizing or enlargement |
| Exact dimensions | Sets every frame to the width and height entered | Matching a required pixel size |
Percentage resizing keeps the original aspect ratio. Exact dimensions use both values as entered, so choosing a different width-to-height ratio will stretch the animation.

GIF Resizer FAQs
How do I resize a GIF online?
Resize a GIF online in three steps: 1. Select GIF files individually, choose a folder, or drag and drop them into the browser. 2. Choose a percentage or enter an exact width and height. 3. Start resizing, preview the results, then download files individually or as a ZIP.
Can I resize an animated GIF without losing the animation?
Yes. The tool resizes every frame and exports the result as an animated GIF rather than a single still image.
Can I resize a GIF by percentage?
Yes. Choose 25%, 50%, 75%, or 100%, or enter a custom percentage. Values below 100% make the GIF smaller, while values above 100% enlarge it.
Can I enter an exact GIF width and height?
Yes. Switch to exact dimensions and enter the required width and height in pixels. Both values must be positive whole numbers.
Does the GIF resizer preserve the aspect ratio?
Percentage resizing preserves the original aspect ratio because the width and height are scaled together. Exact dimension resizing uses the width and height you enter, so the GIF will stretch if those values use a different aspect ratio.
Can I make an animated GIF larger?
Yes. Enter a custom percentage above 100% or use larger pixel dimensions. Enlarging a GIF cannot add detail that is not present in the source, so the result may appear softer or more pixelated.
Does resizing a GIF reduce its file size?
Reducing the dimensions often creates a smaller GIF, but it is not guaranteed. The final file size also depends on the number of frames, colors, transparency, and how the animation is encoded. Review the output size before downloading.
Does resizing change GIF playback speed?
The resize controls change width and height rather than animation speed. To make a GIF play faster or slower, use the Change GIF Speed tool.
What is the difference between resizing, compressing, and cropping a GIF?
Resizing changes the GIF’s width and height. Compression targets file size without requiring different dimensions, while cropping removes part of the visible frame area. Use the GIF Compressor or Crop GIF tool for those tasks.
Can I resize multiple GIF files at once?
Yes. Add multiple GIF files or select a folder, apply the same resize settings, then download results individually or save the completed batch as a ZIP file.
Are my GIF files uploaded to a server?
No. GIF resizing runs locally in your browser, so your files are not uploaded to a server.
Is the GIF resizer free?
Yes. The GIF resizer is free to use, with no registration or credit card required.
