GIF Resize

1. Upload your GIF — Drag and drop a GIF file onto the drop zone, or click browse to pick one from your device. No signup required.
2. Set your new size — Enter exact width and height in pixels, or use the scale slider to resize by percentage. Toggle "Lock aspect ratio" to keep proportions.
3. Download the result — Click "Resize GIF" and when processing finishes, download your resized GIF instantly.

Tip: If you're resizing for a specific platform (Instagram, Twitter, etc.), check their recommended dimensions first. Locking aspect ratio prevents stretching and distortion.

• Social media posts — Instagram, Twitter/X, and Facebook all have different ideal sizes. Resize your GIF to fit each platform perfectly.
• Website optimization — Oversized GIFs slow down page loads. Scale GIFs to their actual display size to improve Core Web Vitals and SEO.
• Email marketing — Newsletters load faster with properly sized GIFs. Smaller dimensions mean happier subscribers and better deliverability.
• Presentation slides — PowerPoint and Google Slides work best with appropriately sized GIFs. Too big and your deck file balloons in size.
• App UI assets — Developers resize GIFs to match different screen densities for smooth performance on all devices.
• Forum & blog comments — Many forums have size limits for embedded GIFs. Resizing ensures your GIF displays without getting rejected.

GIF resizing changes the pixel dimensions of an animated GIF while keeping the animation intact. Unlike simple image scaling that affects only one frame, GIF resizing processes every frame in the sequence to maintain smooth playback.

GifNeo's resizer works in three stages:

• Frame extraction — We decode the GIF and pull out every individual frame along with timing data. This lets us work with each frame as a separate image.
• Smart scaling — Each frame is resized using high-quality interpolation that preserves edges and details. Transparency is handled correctly so backgrounds stay clean.
• GIF reassembly — Resized frames are stitched back together with the original timing, palette, and looping settings for a perfectly animated result.

All processing happens directly in your browser using optimized JavaScript. Your GIF files are never uploaded to any server — your data stays on your device.
