JPG to PDF Converter — Images to One PDF
Turn JPG, PNG or WebP images into a single PDF — A4, Letter or fit-to-image pages, portrait or landscape, with margins — created on your device.
In short
Images become one PDF page each, scaled to fit A4 (210 × 297 mm) or Letter inside the chosen margins, or a page sized to the image at 150 dpi; JPGs up to 2500 px are embedded unchanged and larger photos are downscaled so a 20-photo PDF stays a few MB.
Who this is for: People turning photos or scans of documents into a single PDF for email, portals or printing.
How images become a PDF
- Each image becomes one page. On A4 or Letter the image is scaled to fit inside the margins and centred; fit makes the page exactly the image's size at 150 dpi — best for screenshots and receipts.
- Orientation auto turns landscape photos into landscape pages so they are not shrunk; choose portrait to force a uniform document.
- JPGs up to 2500 px are embedded byte-for-byte (no quality loss); larger photos are downscaled to 2500 px and re-encoded at the chosen quality, which keeps a 20-photo PDF under a few MB.
- Typical uses: scanned ID pages into one PDF for a visa or job portal, phone photos of a signed contract, product shots into a catalogue.

Assumptions
- One image per page; A4/Letter with margins (image scaled to fit and centred), or page sized to the image at 150 dpi.
- JPG/PNG up to 2500 px embedded as-is; larger images downscaled to 2500 px and re-encoded as JPG at the chosen quality.
- Up to 50 images, in file-picker order.
Worked example
Each 4000 × 3000 photo is downscaled to 2500 px and placed on a portrait A4 page → a 6-page, roughly 2 MB PDF ready to email, instead of six 4 MB attachments.
Frequently asked questions
Can I put several images on one page?
Not here — this tool makes one page per image. For a contact-sheet layout, combine images first in an image editor.
Will the PDF be searchable?
No; images have no text layer. Run the image-to-text (OCR) tool on the images if you need the text.
What order will the pages be in?
The order in which your file picker lists them — usually alphabetical by file name. Rename files 01, 02, 03… to control the sequence.
Is there a limit?
50 images per PDF; very large originals are downscaled automatically.
How do I make a PDF from photos on my phone?
Open this page, select the photos in order, choose A4 and Create PDF — it downloads to your phone.
Will the PDF be large?
Photos over 2500 px are downscaled, so 10 photos are typically 2–4 MB.
