About the image compressor
An image compressor reduces file size so pages load faster and uploads fit limits. This one re-encodes JPG, PNG or WebP as optimized JPEG at a quality level you control and shows exactly how many KB you saved — all in the browser, so even sensitive images never leave your device.
Frequently asked questions
Is this tool free?
Yes — completely free, no signup, no watermark and no limits. Startup OG funds the site through its directory and partner program, not paywalled tools.
Is my file or data uploaded anywhere?
No. Everything runs locally in your browser — your file or text never leaves your device and nothing is stored on a server.
How much can I compress an image without losing quality?
For most photos, 70–80% quality cuts file size 50–80% with little visible difference. Drop the slider until the preview just starts to degrade, then step back up.
Does compressing an image reduce its dimensions?
No — compression lowers file size at the same pixel dimensions. Use the image resizer if you also need smaller dimensions.
