Convert JPG to PDF Online — Free

Convert JPG to PDF online — combine one or many JPGs into a single PDF document. Drag to reorder, pick page size, free and browser-based.

How to convert JPG to PDF

  1. 1

    Add your JPG file

    Drop or select a .jpg file. Files up to 50MB process locally in your browser — nothing uploaded.

  2. 2

    Run the conversion

    Each JPG becomes a page in the resulting PDF. Choose page size (A4, Letter, or fit-to-image), orientation (portrait or landscape), and margin width. Drag thumbnails to reorder before generating — the PDF is built entirely in your browser using pdf-lib.

  3. 3

    Download your PDF

    One click saves the result as a .pdf file. Your original file stays on your device.

Why convert JPG to PDF?

PDF is the standard format for documents — printable, signable, searchable (for text layers), and archivable. Combining photos, scanned receipts, or screenshots into a single PDF is far more shareable than zipping a folder of JPGs: one file attaches cleanly to email, fits in a Dropbox link, uploads to a client portal, or prints as a bound document.

Common JPG to PDF use cases

  • Combining receipt photos and invoice scans into a single expense report PDF for accounting or reimbursement
  • Turning a series of whiteboard photos from a meeting into a shareable PDF for colleagues or Notion attachments
  • Packaging product photos into a portfolio PDF for a client pitch, email proposal, or job application
  • Creating a multi-page PDF from screenshots of a bug reproduction or QA test run for Jira or Linear

What file size to expect

Combining 10 smartphone JPGs (each ~3 MB) into one PDF at fit-to-image produces a PDF of roughly 28-32 MB — JPGs are embedded at original quality, so the sum is similar. Choosing A4 with 10mm margins and scaling photos down produces smaller PDFs (12-18 MB for the same 10 JPGs). Pre-compressing JPGs to 500 KB each yields a 5-6 MB PDF.

Technical notes: JPGPDF

JPGs embed in PDF via the DCTDecode filter — the JPG bytestream is included directly without re-compression, so there's no quality loss. Page size options map to standard PDF dimensions: A4 is 210×297 mm (595×842 pt), US Letter is 216×279 mm (612×792 pt), fit-to-image sizes each page to the image's pixel dimensions at 72 DPI. EXIF orientation tags are respected so rotated iPhone photos display correctly. Generated PDFs are PDF 1.7 (Acrobat 8+), compatible with every modern PDF viewer.

Compatibility and browser support

The resulting PDF opens in every modern PDF viewer: Adobe Acrobat, Preview (macOS), Edge, Chrome, Firefox, Safari, iOS Files, Android Drive, and every paid reader (Foxit, PDF-XChange). The conversion itself runs in any modern browser using JavaScript — no server-side processing or upload needed.

Frequently Asked Questions

How many JPGs can I combine?

Up to 20 in one PDF. Each JPG becomes a page in the order you arrange them via drag-and-drop.

Page size options?

A4 (210×297mm), US Letter (216×279mm), or fit-to-image (each page sized to its source image). Margins are configurable from 0 to 50 pixels.

Will the JPGs lose quality?

No — JPG bytestreams are embedded directly via DCTDecode. No re-compression. To shrink the final PDF, compress your JPGs first using our Image Compressor.

Is the PDF searchable?

No — image-based PDFs don't contain a text layer. For searchable scans, use an OCR tool (Adobe Acrobat Pro, Abbyy FineReader) after generating the PDF, or scan with OCR enabled in the source.

Will rotation be preserved?

Yes — EXIF orientation tags on iPhone or Android photos are respected, so portrait photos display right-side-up in the PDF.

What PDF version?

PDF 1.7 (Acrobat 8 and later, released 2006). Compatible with every modern reader.
