Resize animated GIFs to exact dimensions while preserving animation. Choose from presets or custom width with aspect ratio lock.
Compress animated GIFs by reducing colors from 256 to as few as 16, removing duplicate frames, and applying lossy optimization. Reduce file size by up to 80% while keeping animation intact. Essential for web performance, email signatures, and social media where large GIFs cause slow loading.
Edit animated GIFs — resize, change speed, reverse, optimize colors, and extract frames. Perfect for social media memes, product demos, and animated banners.
Convert animated GIFs to APNG (animated PNG) format. APNG supports 24-bit color and 8-bit alpha transparency — better quality than GIF.
Calculate the aspect ratio from width and height dimensions. Find the simplified W:H ratio for images, videos, and screens.
Pretty-prints raw JSON with configurable indent width, key sorting, and bracket collapsing options while flagging syntax errors with exact.

Yes. After the initial page load, GIF Resizer runs entirely on your device with no internet connection needed. All processing is done locally.
Quality depends on the operation. Lossless operations preserve original quality, while compression and format conversion may slightly reduce quality based on your settings.
Most tools support PNG, JPG, WebP, HEIC, GIF, and SVG. Some specialized tools may support additional formats.
Batch processing is available in select tools. For single-image tools, you can process them one at a time.
Completely on your device. Images never leave your browser, ensuring your visual content stays private.
There's no hard limit, but very large images (4000x4000px+) may process slower on lower-end devices due to memory constraints.
Add Text to Photo
Overlays custom text captions onto images with control over font, size, color, alignment, opacity, and rotation angle.
Batch Image Editor
Applies resize, crop, rotate, format conversion, and compression settings to dozens of images simultaneously with one click.
Compress Image to 50KB
Reduces image file size to a specific target — 50 KB, 100 KB, or 200 KB — by automatically adjusting JPEG quality, reducing pixel dimensions, or stripping EXIF metadata. Ideal for government forms, job applications, and upload portals with strict file size limits.
HEIC to JPG
Decodes Apple HEIC photos and converts them to universally compatible JPG files while preserving EXIF metadata like location and camera settings.
Background Remover
Segments the foreground subject from an image using a neural network, producing a transparent PNG. Max 20MB.
WebP to JPG
Converts WebP images into standard JPG format, making them usable in applications and websites that do not support Google's modern format.
