Private image tools that never upload your photos
Compress, convert, resize, crop and watermark images on your own device. Your photos are never uploaded, never stored on a server, and there is no sign-up.
What makes these image tools private
Six promises, and every one is true of every tool.
Never uploaded
Your photos are not sent to a server. They are opened, changed and saved by your own device, so they never travel anywhere.
No sign-up
No account, no email address and no password to forget. Open a tool and use it.
No waiting for uploads
Big photos and big batches start right away, because there is no upload and no download queue. A slow connection doesn't matter once the page has loaded.
Nobody else sees your photos
Not us and not another company's server. Holiday snaps, ID scans and unreleased designs stay between you and your device.
Location removed
Compressing a photo also removes the place and camera details hidden inside it, so the copy you share doesn't show where it was taken.
Free, no daily limit
Sanil.app is free. The only limit is what your device can handle at once. A computer takes whatever it has memory for, while a phone works through photos one at a time and can't open one over 64 megapixels.
How private image tools work
Most online image tools work by uploading your photo to their computer, changing it there, and sending it back to you. That means a copy of every photo you use lands on someone else's server.
Sanil.app turns that around. Your own phone, tablet or computer does the compressing, converting, resizing and watermarking. A photo you drop in is opened, changed and saved right where it is, and nothing is sent to us to change.
The trade is that your device does the work. Very large photos take longer on an older phone, and a huge batch is best done on a computer. That is the price of keeping your photos private, and most people find it a fair one.

Each one works the same way: on your device, never uploaded.
Who needs private image tools
Photographers and designers
Send a client a watermarked preview or shrink unreleased artwork without a copy landing on someone else's server first.
Families
Phone photos of children, homes and holidays carry the place they were taken. Compress and convert them on your device, and the copies you share leave that behind.
Small businesses
Receipts, ID scans, contracts and product photos before a launch are not something to hand to a stranger's server just to make them smaller.
Anyone sharing a photo
Make a picture small enough for an email or an online form without making an account to do it.
Questions about private image tools
Are my photos really not uploaded?
Yes. Everything happens on your device. Your photos are never uploaded and never reach a server, so there is nothing for us to see or keep.
Is there an image compressor that doesn't upload my photos?
Yes. Sanil.app compresses JPG, PNG, WebP, AVIF, GIF and SVG images on your own device, so nothing is uploaded. It converts, resizes, crops and watermarks images the same way.
Can I convert HEIC photos without uploading them?
Yes. HEIC to JPG runs on your device: the photo is opened, saved as a JPG and handed back to you without leaving it. That matters for iPhone photos, which usually show where they were taken.
How can an image tool work without uploading?
Your device does the work itself. When you add a photo, your phone, tablet or computer opens it, changes it and saves the result, the same way it handles a photo in any app. Nothing has to be sent anywhere.
Do you keep copies of my images?
No. Your images never reach us, so there is nothing to keep, nothing to delete and no copy that could be lost or shared.
Do I need an account?
No. There is no sign-up, no email address and no password. Open a tool and drop in your images.
Is it really free?
Yes. Sanil.app is free to use, with no daily limit. The only limit is what your device can handle at once. A computer takes whatever it has memory for. A phone works through photos one at a time, and can't open one over 64 megapixels. For a photo that large, use a computer or resize it first.
Does it remove location data from my photos?
Yes. Compressing a photo removes the location and camera details hidden inside it, so the copy you share doesn't show where it was taken.
What is the seal in the corner of every page?
It is our promise in one stamp: your files are never uploaded and stay local on your device. Select it any time to come back to this page.
