PDF → JPG

Render every page of each PDF to a high-quality JPEG. Output files are named filename_p1.jpg, filename_p2.jpg, etc.

Rendered at 150 DPI using PDF.js (loaded on demand). For large documents, processing may take a moment. Single-page PDFs produce one JPG file.

Selective Merge

Upload PDFs, define a page range or individual pages for each file, then merge only the selected pages into one document.

Enter pages as a range (1-3), individual pages (1,3,5), or a mix (1-3,5,7-9). Leave blank to include all pages. Pages are added in file order.

Pages are re-rendered via PDF.js and re-embedded as compressed images. Text-only PDFs may not shrink significantly — this works best on PDFs containing images or scans.
