FAQ
Is this really free?
Yes. The tool is free to use. We may show ads to support hosting and development.
Do my images get uploaded?
No. All operations happen locally in your browser using JavaScript and canvas. We never see your files.
What format should I export?
We output JPEG in the right resolution for Instagram. That’s ideal for most photos and posts.
Why do my uploads still look blurry on Instagram?
Blurriness can still happen because of Instagram’s own compression or bad network. Using the correct resolution and an optimized preset usually gives the best result.
Make your Instagram images look sharp, not blurry
IGCOMPRESSOR works like an Instagram post sharpener: you choose the final aspect ratio (4:5 portrait, 1:1 square, 9:16 story) and we crop, resize and compress your photo to the exact resolution Instagram expects. This helps reduce the extra compression that often makes Instagram images look soft or pixelated.
Use it as an Instagram image compressor before upload: export from Lightroom or your camera software, drop the file here, set the crop and download a ready-to-post sharp JPEG. It only takes a few seconds and all processing happens in your browser.
Whether you post portraits, car photos or client work, IGCOMPRESSOR helps your Instagram posts stay clean and sharp on the feed, stories and reels.
About IGCOMPRESSOR
IGCOMPRESSOR was built for photographers, creators and brands who want their images to look as sharp as possible on Instagram. Instead of letting Instagram do heavy, unpredictable compression, we resize and optimize your photos to the exact resolutions the app expects.
All processing happens inside your browser, on your own device. RAW files are converted to high-quality JPEG previews, then cropped, resized and lightly sharpened before export, so you can upload crisp, ready-to-post images with minimal quality loss.
