Pre-compressing to 85% puts you in control. Your image is already optimized before Instagram touches it, so their compression has less impact and your photos look sharper in the feed.

FAQ
Common questions
What is the best image size for an Instagram post?+
Instagram recommends 1080 x 1080 pixels for square posts, 1080 x 1350 for portrait, and 1080 x 566 for landscape. Our presets handle all of these — just click the format and download.
Is InstaResizer really free?+
Yes — resizing, compressing, and converting images is always 100% free with no signup. Background removal is free once per day. Pro ($4.99/mo) unlocks unlimited removals, batch processing, e-commerce presets, and an ad-free experience.
Does my photo get uploaded to your servers?+
Never. InstaResizer processes everything in your browser using your own device. Your photos stay completely private — we never see them.
What image formats are supported?+
We support JPG, PNG, WEBP, and HEIC (the format iPhone cameras use). You can also convert between JPG, PNG, and WEBP using the Convert tab.
Why does Instagram make my photos look blurry?+
Instagram recompresses any image over 1MB when you upload. By pre-resizing and compressing with InstaResizer first at 85%, you control the quality — and your photos look noticeably sharper in the feed.
What e-commerce platforms do you support?+
Pro users get presets for Amazon, Shopify, Etsy, eBay, Facebook Shop, Pinterest, and WooCommerce — all pre-sized to each platform's exact requirements. Bulk process up to 50 product images at once.
