Convert JPG to
A4 size PDF
Place one or many images onto standard A4 pages and export a single, print-ready PDF — exactly what forms, assignments, and printers expect. This page opens with A4 page size already selected, so you just add images and convert. It also handles resize image jpg to pdf and how to merge jpg files into one pdf on A4.
Need the images smaller first? Use the image compressor to hit a KB limit, or the image converter to turn HEIC or PNG into JPG before you build the PDF.

Why an A4 size PDF?
A4 (210 × 297 mm) is the standard page size for documents almost everywhere outside North America, so an A4 PDF prints cleanly with no odd cropping and uploads without "wrong page size" errors. This tool scales each image to fit an A4 page with a small margin and centres it, so a phone photo of a form or a scanned page comes out looking like a proper document — not a stretched snapshot. Add several images and each lands on its own A4 page, merged into one PDF in the order you choose.
Need a specific file size too? Set a KB limit — for example jpg to pdf in 300 kb — or use the main JPG to PDF converter and its size presets.
How JPG to PDF at an exact KB works
Building an A4 size PDF from JPGs is two steps: fit each image to an A4 page, then encode the pages into one file. This tool scales and centres every image on A4, and if you set a KB limit it re-encodes the images at a lower quality until the PDF meets it. Everything runs and previews live in your browser, so you see each A4 page before you download.
Add your images
Drop one JPG or many. Reorder them so the pages come out in the right sequence.
Set the target
A4 page size is preselected. Choose orientation and margin, and add a KB limit if needed.
Convert & download
Hit convert. See the final size, then download your PDF. Done.
Why an A4 size PDF matters
Unlike the KB-target pages, this one is about the page shape. A jpg to a4 size pdf lays your image onto a standard 210 × 297 mm A4 page, so it prints and displays like a proper document instead of an odd photo-shaped crop. Use an image to A4 PDF when:
- You need to print it: an A4 PDF comes out of any printer at the right size with no manual scaling.
- A form expects A4: many offices and portals ask specifically for A4 document pages, not free-form image sizes.
- You are merging pages: putting every scan on a matching A4 page makes a tidy, uniform multi-page PDF.
- You also have a KB limit: pick A4 for the shape and still set a KB target — the tool does both at once.

Fitting your image onto A4 neatly
Portrait vs landscape
A tall photo sits best on a portrait A4 page; a wide one on landscape. Match the orientation so your image fills the page without large empty bands.
Centre or fill
The image is placed on the A4 page keeping its aspect ratio, so nothing is stretched. Crop it to roughly A4 proportions first if you want it edge to edge.
Multiple A4 pages
Add several images and each becomes its own A4 page. Reorder the rows so the finished document reads in the right sequence.
A4 and a KB limit together
Need it small as well as A4? Set a KB target too, or pre-shrink a big photo in the image compressor first.
FAQ
Common questions
How do I convert a JPG to A4 size PDF?
Add your JPG (this page already has A4 page size selected), then press Convert to PDF. Each image is scaled and centred on an A4 page, and you can preview every page before downloading.
How do I merge several JPG files into one A4 PDF?
Drop or select multiple images and each becomes its own A4 page. Drag the rows to set the order, then convert them into a single merged A4 PDF.
Can I resize the image to fit A4 without stretching it?
Yes. The tool scales each image proportionally to fit the A4 page and centres it with a small margin, so nothing is stretched or distorted.
Can I also set a file size like 300KB?
Yes. Keep A4 selected and choose a KB limit or type your own — for example 300KB — and the tool compresses the images so the A4 PDF meets that size.
Portrait or landscape A4 — which should I use?
Leave orientation on Auto and each page follows its image; choose Portrait or Landscape to force every A4 page one way, which is handy for a consistent printed document.
Are my files uploaded to a server?
No. The whole JPG to A4 PDF conversion runs locally in your browser. Your images and the finished PDF never leave your device.
Is this the same as an image to A4 PDF converter?
Yes. It takes JPG, JPEG and PNG, so "jpg to A4 size PDF" and "image to A4 PDF" are the same thing here — each image is placed on a standard A4 page in the finished PDF.
