GIF Compressor – Shrink Animated GIFs Online Free

About This Tool

Introduction

Trencada's free gif compressor shrinks animated GIFs right in your browser — no uploads, no signup, and no watermark. If your GIF is too large to share on social media, embed in a blog post, or send in a chat app, this tool cuts its file size by reducing the number of colors per frame, resizing the dimensions, dropping frames, or combining all three. Everything is decoded and re-encoded locally on your device using proven open-source libraries, so your images never leave your computer. The result is a smaller, still-animated GIF you can preview and download instantly.

How to Use

1. Add your GIF — drag and drop an animated GIF into the dashed upload box, or click the box to browse your files. Animated GIFs up to 60 MB are accepted.
2. Choose your compression settings:
   • Colors per frame — 256 colors for best quality, 128 for a balanced result (default), or 64 / 32 colors for much smaller files.
   • Max width — keep the original size, or cap the width at 800, 600, 480, or 320 px (height scales proportionally).
   • Frames — keep all frames, or keep every 2nd or 3rd frame. Frame timing is adjusted automatically so playback speed stays natural.
3. Click “Compress GIF” — a progress bar shows decoding and encoding frame by frame. Larger GIFs take a little longer.
4. Review and download — compare the original size, compressed size, and percentage saved; watch the animated preview; then click “Download compressed GIF” to save it. Use Reset to start over with a new file.

FAQ

Is my GIF uploaded anywhere?
No. Compression happens 100% in your browser using JavaScript. Your file never leaves your device, so it is safe for personal or sensitive images.

Why is my GIF still big after compressing?
Some GIFs are already well optimized. Try stronger settings: 64 or 32 colors per frame, a smaller max width (e.g. 480 or 320 px), or keep every 2nd/3rd frame. The tool warns you when the result isn't smaller and suggests what to try next.

Will my GIF still be animated?
Yes. All kept frames are re-encoded with their original timing (adjusted when frames are skipped), so the downloaded file plays as an animation.

What files can I compress?
Animated GIF files up to 60 MB. Non-GIF files are rejected with a friendly message.

Is transparency preserved?
Transparency is preserved as far as the GIF format allows during re-encoding.

Does it work on mobile?
Yes — the tool layout is fully responsive and runs in any modern mobile or desktop browser.
