ImgKit Compress, resize and convert right here in the browser tab — and remove a background or blur every face without the photo ever reaching a server.

Which side is #
77% smaller?
Drag the handle. One half is 77% lighter than the other, and it was compressed right here in a browser tab — see if you can find the seam.
AI, on your device
The hard part #
is the hair.
Most background removers turn loose strands into mush. Drag the handle and look along the edge of the hair: this is the model's raw output on this photo, with no touch-ups, produced on the device you're reading this on.
- Transparent PNG or WebP, ready to drop onto any background
- The photo never leaves your browser — no upload, no account
- 26 MB model, downloaded once and then reused from the browser cache
What it does
Four things it #
does well.
No sign-up flow, no watermark, no upsell at the end. Drop a file in, get a file back, close the tab.
Blazing fast
Your device does the work. No waiting on uploads or servers.
AI that stays put
Background removal, face blur and upscaling run on your device — not on someone's server.
Tiny files
Smart compression cuts weight without visible quality loss.
Nothing to sign up for
No account, no watermark, no daily limit. Drop a file in, take it back, close the tab.

Whatever your #
phone shoots.
iPhone HEIC photos come out as JPG that opens anywhere. PNG, WebP and AVIF convert in either direction, and nothing gets a watermark.

Privacy, not a promise
Turn off your wifi. #
It still works.
The tools run inside the tab you already have open, so pulling the network doesn't stop them. There's no upload endpoint, no storage bucket and no account to create. Close the tab and the files are gone.
That matters most for the photos you'd think twice about up. Blur every face in a picture, cut a person out of a background, or read the text off an ID — the models download once and then run here, on your device. Most tools that do this send the photo to a server first.

Good to know
Things people ask. #
Are my images uploaded anywhere? #
No. ImgKit runs entirely in your browser. Your files are processed locally and never leave your device.
Which image formats are supported? #
You can optimize JPG, PNG, WebP and AVIF images, plus HEIC photos from iPhone. JPG and HEIC export as JPG; PNG, WebP and AVIF export as WebP, which keeps transparency.
Does the AI run on my device too? #
Yes. Background removal, face blur, upscaling and text recognition all run in your browser. The model file downloads once and is then reused offline — the image itself is never sent anywhere, which is the whole point for a photo of someone's face or an ID.
Is ImgKit really free? #
Yes. The core optimizer is free to use with no account and no watermark, for files up to 50 MB.
Will compression reduce image quality? #
ImgKit balances size and quality for you. Fine-tune the quality slider and check the preview before down. If an image is already as small as it gets, you'll get the original back.
Go fix #
that image.
No sign-up, no watermark, nothing uploaded. Free for files up to 50 MB.
