Instagram always re-compresses your photos. By uploading at the right quality and dimensions, you can minimize the double-compression quality loss. This tool helps you find the sweet spot.
Instagram compresses all uploads. If you upload a 10MB photo, Instagram compresses it aggressively. If you pre-compress to the right size, Instagram applies less compression = better final quality.

Frequently Asked Questions
Why does Instagram reduce my photo quality?
Instagram compresses all uploads to save storage and bandwidth. Pre-compressing to 1080px wide, JPEG 85%, under 1MB minimizes the additional compression Instagram applies.
What is the best format for Instagram?
JPEG at 85% quality, 1080px wide. Instagram converts everything to JPEG anyway, so starting with JPEG avoids double format conversion.
Does file size affect Instagram quality?
Yes. Larger files get more aggressive compression. Keeping under 1MB results in less quality loss after Instagram processes it.
