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 grey 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.
How it works
- Drop your files onto the box above, click it to browse, or paste from the clipboard.
- Adjust the options if you need to — the defaults suit most cases.
- Press Convert. The work happens on your device, so speed depends on your computer or phone.
- Download the PDF — individually or all at once.
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.
