Hoq Capture
Scan receipts and pages to PDF in your browser. Nothing to install.
What it does
Open capture.hoq.app on a phone or laptop and point the camera at a receipt or a page. It finds the four edges, straightens the page and adds it to a stack. When the page holds still it takes the shot for you.
The work happens on your device. Edge finding runs in a small WebAssembly engine in the page, and the photos stay in your browser's own storage until you export. If you are not signed in, nothing is uploaded.
Export a PDF, a JPG, or a zip of JPGs. Turn on Searchable text and the PDF gets an invisible text layer from on-device OCR, so you can search and copy from it. Signed in, a PDF goes straight into your Hoq Storage drive.

Specifications
| Where it runs | In the browser tab, on your device. Edge detection, straightening, filters and OCR all run locally. |
|---|---|
| Install | None. It is a web page you can add to your Home Screen. |
| Export formats | PDF (optionally searchable), a single JPG, or a zip of JPGs for several pages. |
| Searchable PDF | On-device OCR writes an invisible text layer. The text layer holds Latin (WinAnsi) characters only. |
| OCR download | About 16 MB of model weights, fetched the first time you ask for searchable text. |
| Export sizes | Original, medium (2200 px long edge) or small (1400 px long edge). |
| Page filters | Original, color, gray and black and white. Filters can be changed later without retaking. |
| Where pages wait | In your browser's IndexedDB on the device, so a backgrounded tab does not lose them. |
| Saving to the cloud | Only when signed in with Hoq ID: the PDF goes to your Hoq Storage drive. Otherwise it downloads. |
| Other input | Choose, drop or paste an existing image instead of using the camera. |
