Does it work on a laptop?

Yes, with a webcam, or by choosing photos you took earlier. The camera mode is most convenient on a phone, where “Choose photos” can also open the camera directly.

Does it straighten or crop the page automatically?

Not yet — frame the page so it fills the picture. If a photo needs trimming, run it through Crop Image first, then add it here.

Can I make the scan searchable?

Yes. After saving, run the PDF through OCR PDF.

Point your camera at each page and capture. The document filter whitens the paper and sharpens the text, and the pages are collected into one PDF — no scanner app required.

Why convert JPG to PDF

Scanner apps want subscriptions or permissions; this page does the core job in the browser: capture from the camera or pick existing photos, level the exposure so gray photos of paper become clean white pages, and stack them into a PDF.

Add pages one after another, remove any you do not like, and export. Frame the page so it fills the picture — the filter works best when the paper is flat and evenly lit. Run OCR PDF afterwards if you want the result searchable.

About the formats

JPG · JPEG image · .jpg

The universal photo format: small files, supported by every device, camera and website, but no transparency and slight quality loss on each save.

JPEG compression discards fine detail the eye rarely notices; quality 80–90 is usually indistinguishable from the original at a fraction of the size.
Re-saving a JPG repeatedly adds generation loss, so keep an original and export copies.
JPG has no alpha channel — transparent areas become white or black when converted from PNG.

PNG · Portable Network Graphics · .png

Lossless image format with transparency, ideal for screenshots, logos, icons and graphics with sharp edges or text.

PNG is lossless: every pixel is preserved, which is why photos saved as PNG are 5–10× larger than JPG.
Supports an 8-bit alpha channel, so edges can be partially transparent.
Most browsers and apps have supported PNG since the late 1990s.

HEIC · High Efficiency Image Container · .heic

The default photo format on iPhone and iPad since iOS 11: about half the size of JPG at the same quality, but poorly supported outside Apple devices.

HEIC stores images with the HEVC (H.265) codec; a container can hold several images, such as a Live Photo or burst.
Windows needs a paid HEVC extension to open HEIC files, and many websites and forms refuse them.
iPhone can be set to shoot JPG instead: Settings → Camera → Formats → Most Compatible.

WebP · WebP image · .webp

Google’s web image format: 25–35 % smaller than JPG at the same quality, supports transparency and animation, but not every desktop app can open it.

WebP has both lossy and lossless modes, and both support transparency.
All modern browsers support WebP; older image editors, Windows Photos before 2020 and many print workflows do not.
Right-clicking and saving an image from a website often gives you a WebP file even if the page shows a JPG.
