Why convert PDF to JPG?
- Share a page anywhere — images display directly in chats, social media and presentations.
- Use in other apps — insert pages into slides, documents or image editors.
- Thumbnails and previews — create preview images of documents for websites.
How the conversion works
Each selected page is rendered by PDF.js at the chosen resolution onto a white background and saved as a JPG at high quality. Pages are processed one at a time to keep memory use low.
What is a PDF file?
PDF (Portable Document Format) was created by Adobe and is now an open ISO standard (ISO 32000). A PDF fixes the exact layout of every page — fonts, images and positions — so a document looks the same on every screen and printer. That makes it the standard for contracts, invoices, manuals, papers and forms.
Inside, a PDF stores each page as drawing instructions. Text written by a program is stored as real characters (a “text layer”) and can be selected and extracted. Scanned documents usually store only a picture of each page, so their text cannot be extracted without OCR.
What is a JPG file?
JPG (or JPEG) is the most common photo format. It uses lossy compression that discards detail the eye barely notices, which keeps files small — ideal for photos, scans and sharing by email or messenger. Every device, browser and image app can open it.
JPG does not support transparency, and repeated re-saving slowly reduces quality. Cameras and phones also store an orientation tag (EXIF) that tells apps how to rotate the picture for display.
