Image compressor

Smaller files, same look.

Drag the quality slider, watch the size drop live, download when happy. Your photo never leaves this device.

Everything happens on your device. 80% quality is visually identical for most photos at a fraction of the size; very large images are also scaled to a maximum of 2400px on the long side.

See the trade-off before you commit

Compression is a bargain between size and quality — the only way to strike it well is to watch both change live. The slider shows the compressed size and preview instantly, so you stop at exactly the point where your eyes notice nothing but your file is 5× lighter.

Why smaller files win on social

Faster uploads on mobile data, faster WhatsApp sends to clients, faster web pages if you run a portfolio — and Instagram's own compressor behaves better when it isn't handed a 12MB monster.

On-device, always

Like every InstaGrab studio tool, the compressor runs entirely in your browser. No upload queue, no privacy question, no server ever sees your photo.

No hard limit — big camera files are also scaled to 2400px on the long side, which is more than any social platform displays.

No — compression runs on your device via the browser's canvas API. This page works even offline once loaded.
