GIF Resizer

Adjust the width and height of GIF animations, supporting 2x enlargement, 2x reduction, and custom sizes. You can lock the aspect ratio to keep the animation from distorting.

Select a GIF, set size options, then process and download the result.

Resize single or batch GIFs. Only the first 20 files are shown for review; all selected files will be processed.

File list No files selected

After selecting GIFs, the first 20 files, dimensions, and sizes will appear here. In batch mode, filenames are kept by default; duplicates get numbers added.

Select GIF files

You can select multiple GIFs. Choose files first, then set size options in the next step.

Click to select GIFs, or drag files here Supports .gif / image/gif, with batch selection. Files are processed only on this page.

Set size options

Choose a resize mode and output settings before processing. Batch processing uses the same settings for all files.

Resize Mode Custom mode supports locking aspect ratio

Scale by percentage Resize by original proportions, ideal for keeping each file's ratio in batch. Scale down 2x Reduce width and height to 50%, commonly used to shrink display size. Scale up 2x Increase width and height to 200%, for larger display needs. Custom size Manually enter target width and height, with aspect ratio lock support.

Instructions

Software Usage Instructions

Select GIF files: Click the “Select GIF Files” button and choose the animated GIFs you want to resize; you can also select multiple GIF files in bulk.
Confirm file information: After selecting files, the tool will display the names, dimensions, frame counts, and sizes of the first 20 files. Files beyond 20 will still be included in processing.
Select a resize mode:
- Percentage scaling: Resize proportionally based on the original dimensions, suitable for batch processing while preserving each GIF’s aspect ratio.
- Reduce by 2x: Adjust the width and height to 50% of the original, suitable for reducing display size.
- Enlarge by 2x: Adjust the width and height to 200% of the original, suitable for animated images that need to be displayed larger.
- Custom size: Manually enter the target width and height, suitable for avatars, web images, social platform dimensions, and similar use cases.
Set processing parameters:
- Lock aspect ratio: Automatically calculate the height when changing the width to prevent image distortion.
- Smooth scaling: Makes the edges of standard animated images smoother; it can be turned off for pixel-art GIFs.
- Preserve transparent background: Attempts to preserve the original transparent areas of the GIF.
- Color dithering: Improves transition effects in some animated images with gradients or complex colors.
- Keep original filenames for batch files: Uses the original filenames for batch output, and automatically adds numbers if duplicate names occur.
Save settings: Click “Save Settings” to keep commonly used sizes, scaling methods, and encoding parameters.
Start processing: Go to the “Process & Download” step, click “Start Resizing,” and wait for frame-by-frame processing to complete.
Download results: A single GIF can be downloaded directly after resizing; multiple GIFs will be generated as a ZIP archive for download.

FAQ

A: Percentage scaling resizes each GIF proportionally based on its original width and height, making it suitable for batch processing animated images of different sizes. Custom size outputs according to the entered width and height, making it suitable for cases with specific pixel requirements.

A: Locking the aspect ratio preserves the GIF’s original proportions. When you change the width, the height is automatically calculated proportionally, preventing people, icons, or text from being stretched horizontally or vertically.

A: Yes. The tool reads and redraws the GIF frame by frame, then re-encodes it using the original frame delays to preserve the original animation timing and playback as much as possible.

A: Smooth scaling is recommended for regular photos, meme GIFs, and illustrated GIFs. For animated images such as pixel art or retro game footage where sharp pixel edges need to be preserved, you can turn this option off.

A: The original file name is kept by default. If duplicate names occur in a batch, the tool automatically adds a number after the file name to distinguish them. You can also turn off keeping the original name and use the configured suffix to generate new file names.

A: GIF is a bitmap format, so enlarging it requires interpolation to add pixels, which may make the image look softer. We recommend limiting the enlargement ratio or using a higher-resolution source file before processing.
