JPG to PDF Converter

Turn JPG photos into one PDF or one PDF per image. A4, Letter or fit-to-photo pages, margins, no recompression and an optional size limit in KB.

Pages follow the order you select the files in (or sort them by name below).
Optional. Photos are recompressed and scaled down only as much as needed to fit.

Turn phone photos, scanned receipts or screenshots saved as JPG into a PDF that any office, school or government portal will accept. The original JPEG data goes into the PDF untouched, so there is no extra quality loss, and photos taken sideways are turned upright from their EXIF orientation. Everything runs in your browser; nothing is uploaded.

How to use this tool

  1. Select your JPG files — pages follow the order you choose them, or sort them by name.
  2. Pick the page size: A4, Letter, Legal, or the same size as each photo.
  3. Choose the orientation, a margin and whether photos fit inside the page or fill it.
  4. Optionally enter a size limit in KB if a website caps the upload, then download the PDF.

Formula

Each photo is scaled by k = min(page width − 2 × margin ÷ photo width, page height − 2 × margin ÷ photo height) to fit, or by the larger of the two ratios to fill the page. Photo size in points = pixels × 0.75 (96 DPI).

A4 is 595.28 × 841.89 pt (1 pt = 1/72 in). With a size limit, the tool first tries the original data, then keeps JPEG quality between 55% and 92% while scaling the photos down step by step, and only then allows quality down to 30%.

Example

A 4032 × 3024 px phone photo (3024 × 2268 pt at 96 DPI) on A4 with Automatic orientation lands on a landscape A4 page (297 × 210 mm). With no margin, k = min(841.89 ÷ 3024, 595.28 ÷ 2268) = min(0.278, 0.2625) = 0.2625, so the photo is drawn 793.7 × 595.3 pt: full height, with narrow white bands of about 24 pt (8.5 mm) on the left and right.

Size limits for upload portals

Many application forms accept PDFs only under 100, 200 or 500 KB. Enter that number in “Keep each PDF under” and the tool recompresses only as far as needed, so the result stays as sharp as the limit allows. If even the smallest version is too big, the result says so — split the photos over several PDFs instead.

Frequently asked questions

Does converting reduce photo quality?

No, unless you set a size limit. The JPEG data is copied into the PDF byte for byte, without the camera’s EXIF block.

Why was my sideways photo turned upright?

Phones store the camera’s orientation in EXIF instead of rotating the pixels. The tool reads it and rotates the photo on the page, without re-encoding it.

Can I mix PNG files in?

Yes — PNGs are embedded losslessly. For WebP, HEIC and other formats use the Image to PDF converter.
