Frequently Asked Questions
- How do I compress photos for Instagram?
- Upload your photo to SizeSnap, set the target to 30MB or less, and click Compress. Pre-compressing avoids Instagram's aggressive re-compression, which can blur fine details.
- What is Instagram's photo size limit?
- Instagram allows photos up to 30MB. However, the platform re-compresses all uploads to around 1-2MB for feed delivery, so pre-compressing gives you more control over the final quality.
- Does compressing photos before posting to Instagram help?
- Yes. When you pre-compress to a reasonable size, Instagram's algorithm has less work to do, which often preserves more detail — especially in textures, gradients, and low-light shots.
