Instagram automatically compresses your photos when you upload them — and not always in a good way. The result? Blurry, washed-out images that don't do justice to your original photo. The solution is simple: compress your images yourself before uploading, so you control the quality.
Instagram has strict file size limits to save storage and bandwidth. When your image is too large, Instagram's algorithm automatically reduces the quality — often aggressively. This is why your perfectly sharp photo looks blurry after posting.
| Post Type | Resolution | Max File Size |
|---|---|---|
| Square Post | 1080 x 1080px | 8MB |
| Portrait Post | 1080 x 1350px | 8MB |
| Landscape Post | 1080 x 566px | 8MB |
| Story | 1080 x 1920px | 30MB |
💡 Pro Tip: Set quality to 80% for most photos. For detailed landscape shots or portraits, use 85%. Your images will look sharp on Instagram while loading fast.
Always use JPEG for Instagram photos. PNG files are larger and Instagram will compress them more aggressively. JPEG at 80% quality gives you the best results.
| Original Size | After Compression | Saving |
