Free tools

File chores, done privately.

Compress a PDF, remove a background, resize a photo to the exact KB, copy text out of an image, and for India, size exam-form photos and mask an Aadhaar. These run in your browser, so your files never leave your device, and they cost nothing to run. No sign-up, no watermark, no daily limit.

Nothing is uploaded. Check your browser's network tab if you like.

An AI agent in your browser (Gemini in Chrome, the ChatGPT browser) can run these tools too, through WebMCP; your files still stay on your device.

Safe Aadhaar copy

Unlock your e-Aadhaar, hide all but the last 4 digits, stamp what it's for, and keep it small enough to upload.

Compress a PDF, to the KB

The person, cut out as a transparent PNG or on plain white, for passport and exam photos. No watermark, no limit.

Copy the words out of a photo, screenshot, scan or PDF: English, Hindi, Bengali, Tamil, Telugu, Urdu and more.

Open

Cold email

A cold email written from a company's website, the footer US law asks business email to carry, and how many emails Gmail lets you send.

Questions

Are these tools really free, with no upload?+

Yes. Each one runs inside your browser, so your files never leave your device and there is nothing for us to meter: no sign-up, no watermark, no daily limit. The only downloads are the tools' own models, fetched from sochen.dev the first time you use them. You can check in your browser's network tab.

Which tool do I need for an exam form?+

The photo and signature resizer for the JPEGs (photo, signature, thumb, declaration), with the sizes from the notice filled in. The compress-PDF tool for certificates that must be under a size, and the images-to-PDF tool when you only have photos of them.

Can an AI agent in my browser use these tools?+

Yes. Through WebMCP, an agent in Chrome or the ChatGPT browser can run the tools on this site on a file you have added to the page; the file still stays on your device.

A whole form to get ready? Say it once.

“Get my IBPS photo, signature, thumb and declaration ready.” Sochen does all four in one go, checks each against the notification, and your files still stay on your device.
