Will files be uploaded? Is JPG to PDF safe?

JPG to PDF runs 100% in your browser via File API; no network upload, memory cleared when you close the tab.

Processing failed or download blocked?

Check page ranges, passwords and file integrity. If the browser blocks multiple downloads, allow automatic downloads or click one by one.

How to chain with other tools?

Configure & process — Set pages, angle, password or quality, then hit “Calculate / Process”. JPG to PDF runs via WebAssembly and pdf-lib in your browser — no server queue.
Preview & download — Check pages, size and thumbnails on the right, then download. Batch jobs download one by one; tweak and re-run if needed.

Tips & Notes

Page syntax: Use 1,3,5-7 or 1-10,15; empty means all. Out-of-range pages are ignored.
Privacy & size: Everything runs locally — no server upload. For large files, process in batches of 50–100 pages.
Fidelity: Fonts and vectors are preserved where possible. For scanned PDFs, run OCR/searchable PDF first, then convert.

FAQ

Merge multiple JPGs to one PDF sharp?

JPG to PDF supports single/batch with “fit/fill/original” layouts, auto A4 and color/transparent preservation — for portfolios. Sort by filename or drag chips, pick “high quality”, preview each page for sharpness.

PNG/WebP/HEIC supported?

Yes. JPG, PNG, WebP, HEIC, TIFF, BMP, SVG via “Image to PDF” or single-format tools, auto-detect and uniform layout — for phone albums. HEIC via heic2any → JPEG → PDF, all locally.

Control page size/orientation?

Default A4 portrait, pick “landscape” or “original” to keep aspect — for posters vs resumes. After conversion, tweak with “Rotate PDF” and “Compress PDF” for print vs web.
