What is Twitter's GIF size limit?

Twitter limits GIFs to 5MB on the web and 3MB on the mobile app. The mobile limit is strictly enforced — if your GIF works on a phone, it works everywhere on Twitter.

Does Twitter convert GIFs to MP4?

Yes. Twitter automatically converts all uploaded GIFs to MP4 on their servers. This server-side re-encoding can degrade quality. Compressing your GIF to a smaller size before uploading gives Twitter less data to work with, often resulting in less aggressive re-encoding and better final quality.

What dimensions should Twitter GIFs be?

Twitter displays GIFs at 500-600px wide in the feed. A 16:9 aspect ratio (1200x675) or 1:1 square (800x800) are the most common. Resize to these dimensions before compressing for best results.

Why does my GIF look worse on Twitter after uploading?

Twitter re-encodes all GIFs to MP4 on their servers, often with aggressive compression settings. To minimize quality loss: compress your GIF before uploading to keep the file small, use Balanced mode, and avoid complex gradients that break during re-encoding.

Twitter GIF Size Rules — What Actually Works

Twitter's GIF rules are deceptively simple but subtly different from other platforms. The key thing to understand is that Twitter does not actually serve your GIF — it converts every GIF to MP4 on upload. Your "compressed GIF" is received, re-encoded, and served as video. This means your compression strategy on Twitter is fundamentally different from Discord or email.

Platform	Max GIF size	Serves as	Key constraint
Twitter Web	5MB	MP4	16:9 or 1:1 ratio. Desktop first.
Twitter Mobile	3MB	MP4	Stricter enforcement. The real limit.
Twitter Ads	1MB	MP4	Strictest. Maximum mode required.

The Twitter MP4 Problem — and How to Beat It

Twitter converts every GIF to MP4 using server-side re-encoding. This is not optional — it happens to every GIF, every time. The problem: Twitter's re-encoding is aggressive and often produces visibly degraded results, especially on GIFs with text, fine details, or smooth gradients.

The counterintuitive solution: upload a smaller, pre-compressed GIF. When Twitter receives a compact, optimized GIF, the re-encoder has less work to do and produces a cleaner MP4. When it receives a bloated 15MB GIF that barely squeaks under the limit, the re-encoder must work aggressively, producing visible artifacts.

Think of it like sending a photo to a printer. Send a clean, properly sized image and you get a sharp print. Send a pixelated mess and the printer's scaling makes it worse.

Step-by-Step: Compress a GIF for Twitter

1. Start with the right dimensions. Resize to 600px width. Twitter displays GIFs at this width in-feed. Anything larger wastes data and makes the re-encoder work harder.
2. Click the < 5MB Twitter preset. This targets the web limit. For guaranteed mobile compatibility, click it again and aim for under 3MB.
3. Choose your mode based on content. Quality mode for photos and gradients (20-35% savings). Balanced mode for general content (35-55% savings). Maximum mode for memes and simple graphics (50-70% savings).
4. Test before posting. Use the live comparison slider to verify quality. Pay special attention to text readability — Twitter's re-encoding is hardest on small text.
5. Upload the compressed GIF. Twitter will re-encode it, but because the source is compact and clean, the result will be much closer to your original quality.

Best Aspect Ratios for Twitter GIFs

Twitter crops or letterboxes GIFs to fit its feed layout. Using the right aspect ratio prevents unexpected cropping:

Feed post (16:9)

1200x675px

Most common. No cropping.

Square (1:1)

800x800px

Works everywhere. Safe choice.

Vertical (9:16)

1080x1920px

Video tab. May be cropped in feed.

Twitter GIF Compression Cheat Sheet

GIF type	Target size	Mode	Tip
Reaction / meme	under 2MB	Balanced 60-80	Resize to 500px first. These GIFs live fast.
Product showcase	under 3MB	Quality 40-60	Preserve detail. Avoid gradients.
Text-heavy infographic	under 3MB	Quality 30-50	Text readability is priority. Do not over-compress.
Twitter Ad creative	under 1MB	Maximum 70-90	Consider converting to MP4 directly.
