What is Twitter's image upload size limit?

Twitter accepts images up to 5MB for photos, and up to 15MB for GIFs. PNG files can be up to 5MB.

Does Twitter compress images?

Yes. Twitter converts all uploaded images to JPEG and applies its own compression. Pre-compressing at 85% quality before uploading minimizes the visible effect of Twitter's additional compression.

What are the best image dimensions for a Twitter post?

1200×675px (16:9 ratio) for single images in tweets. 1200×1200px for square images. Twitter displays images in a cropped preview in the timeline — using 16:9 ensures the full image is visible.

Should I use PNG or JPG for Twitter?

JPG is recommended for photographs. PNG is better for graphics with text or sharp edges, as PNG-to-JPEG conversion can add artifacts. Twitter will convert PNGs to JPEG anyway, so starting with JPG avoids double-compression.

Why do my Twitter images look pixelated?

Twitter's JPEG conversion is aggressive for large files. Ensure your image is under 1MB and at the correct dimensions. Images under 1MB at 1200×675px typically survive Twitter's compression without visible degradation.

How to use this tool

💡

Compress to 85% JPG quality at 1200×675px. This is small enough for Twitter not to aggressively recompress, and sharp enough to look good in the timeline.

How It Works

Step-by-step guide to compress image for twitter / x:

1
Resize to Twitter dimensions
Use the Image Resizer to set your image to 1200×675px (16:9 ratio for single tweet images).
2
Convert to JPG if needed
Twitter converts all images to JPEG. Use the Format Converter to convert PNG to JPG first to avoid double-conversion artifacts.
3
Compress to 85% quality
Upload the JPG to the Image Compressor, set quality to 85%, and download.
4
Upload to Twitter/X
Attach the compressed image to your tweet. It should display sharply without further quality loss.
