🔍 PDF Conversion Guide & Technical Info

About JPG to PDF

A JPG to PDF converter merges one or more images into a single, portable PDF document. Instead of sending a folder full of loose photos, you get one tidy file that opens identically on any phone, tablet or computer — perfect for receipts, scanned paperwork, portfolios and homework.

A PDF preserves your page order, layout and image quality in a format every device and printer understands. It is the universal standard for sharing documents: it cannot be accidentally re-ordered, it prints predictably, and it can hold dozens of pages in a fraction of the space of separate image files.

Everything runs locally in your browser. Your photos and documents are never uploaded to a server, which keeps private receipts, contracts and ID scans completely confidential. Add as many images as you like, drag them into the right order, choose a page size, and download one finished PDF.

Create PDFs for Specific Needs

Receipts & Expense Reports

Combine photos of receipts into one PDF for reimbursement or taxes. A single document is far easier to email and archive than a dozen separate snapshots.

Scanned Documents & Contracts

Turn phone photos of signed paperwork into a clean multi-page PDF. Use A4 or Letter page size so it prints correctly on standard office printers.

Portfolios & Photo Albums

Bundle artwork, designs or event photos into one shareable PDF. Fit-to-image sizing keeps each picture edge-to-edge with no white borders.

School & Homework Submissions

Many learning platforms accept only PDF uploads. Convert photos of handwritten work or worksheets into a single file that submits in one step.

Page Size Comparison

A4 vs Letter vs Fit to Image — Choosing the Right Page

Page Size Description
A4 (210 × 297 mm) The international standard for documents and printing. Use it for receipts, contracts and anything destined for a printer outside North America.
Letter (8.5 × 11 in) The default office size in the US and Canada. Pick this for North American printing so margins and scaling come out correctly.
Fit to Image Each page matches the exact dimensions of its image — no borders, no cropping. Ideal for photo albums, portfolios and full-bleed artwork.
Legal (8.5 × 14 in) A taller page for legal forms and long tables. Use it when content runs past the bottom of a standard Letter page.

Quality, Size & Privacy

A few practical rules keep your PDFs sharp, small and safe:

  • Higher image quality means a larger PDF — balance clarity against file size for email
  • Fit-to-image avoids white borders; fixed sizes (A4/Letter) are better for printing
  • Drag images to reorder pages before exporting — the sequence is preserved exactly
  • Photos taken in good light scan far more legibly than dim or angled shots
  • Everything is processed locally, so sensitive documents never leave your device

For the best result, photograph documents flat and well-lit, order your pages first, then export once at the size that matches how the PDF will be used.


📐 Formulas and Algorithms

Laying images onto PDF pages comes down to a little geometry and unit conversion.

Points per Page 1 inch = 72 pt · A4 = 595 × 842 pt

PDF measures everything in points; an A4 page is 595 by 842 points.

Scale to Fit Scale = min(PageW / ImgW, PageH / ImgH)

The image is scaled by the smaller ratio so it fits the page without distortion.

Centering Offset X = (PageW − ImgW × Scale) / 2

Leftover space is split evenly to center the image on the page.

DPI for Print DPI = ImagePixels / PageInches

Aim for 150–300 DPI so the printed page looks crisp rather than blocky.

Estimated File Size Size ≈ Σ (each image's compressed bytes)

A PDF of photos is roughly the sum of its images plus a small structural overhead.

❓ Frequently Asked Questions

Q: Can I combine multiple images into one PDF?

A: Yes. Add as many images as you like, drag them into the order you want, and they become consecutive pages in a single PDF.

Q: How do I change the page order?

A: Drag and drop the image thumbnails before exporting. The PDF keeps exactly the order shown on screen.

Q: Are my images uploaded to a server?

A: No. Everything is processed locally in your browser, so receipts, contracts and personal documents never leave your device.

Q: What page size should I choose?

A: Use A4 or Letter for documents you will print, and Fit to Image for photo albums or artwork where you want no borders.

Q: Will the PDF reduce my image quality?

A: Images are embedded at high quality. You can lower the quality setting to shrink the file for email, but the default keeps photos sharp.

Q: Does it work with PNG and other formats?

A: Yes. JPG, PNG, WebP and other common image formats can all be combined into a PDF, despite the tool's name.

Q: Is there a limit on the number of images?

A: You can add many images at once. Because processing is local, the practical limit depends on your device's memory rather than a server quota.

Q: Can I make a PDF on my phone?

A: Yes. The tool runs in any modern mobile browser, so you can photograph documents and build a PDF directly on your phone.

Q: How do I fit each photo to its own page?

A: Choose the Fit to Image page size. Every page then matches its image exactly, with no white margins or cropping.

Q: Is the converter free to use?

A: Yes, it is completely free with no watermarks, no sign-up and no limit on how many PDFs you create.
