This image to PDF converter is for the search “JPG to PDF”: a landlord portal, a visa site, or a professor’s dropbox will only take .pdf. Convert image to PDF when you need a photograph of a passport, a receipt, or a whiteboard sitting on a PDF page so the uploader stops rejecting JPEG. PNG to PDF is the same wrap — one still, one page. Convert photo to PDF here is not Acrobat, not OCR, and not a ten-file binder.
Convert image to PDF — one file, one page
The widget above converts one file per job. Select five photos and you get five PDFs. Sites like iLovePDF built their homepage around “combine images into one PDF.” We did not. Photos to PDF as a single binder is a merge product. If you need exhibits 1–12 in one packet, convert image to PDF here then merge elsewhere — or use a scanner app that already exports a multi-page PDF (Notes on iOS, Adobe Scan, Microsoft Lens).
What actually lands in the file
We decode the image (JPG, PNG, WebP, or a still GIF), apply EXIF rotation so a phone photo taken in portrait is not a landscape slab, flatten any alpha onto white, encode JPEG at quality 90, and embed that JPEG in a PDF page sized at 150 DPI. A 3000×2000 photo becomes a page about 20×13.3 inches at that mapping — large on screen, reasonable for print of a photo. It is not magically A4 unless your pixels already match A4 at 150 DPI (roughly 1240×1754). We do not letterbox onto A4, we do not add margins, we do not put a filename in a header.
That last point bites people who expected “print ready letterhead.” If you need 8.5×11 with a 0.5" margin, crop or pad the image in an editor first, or use Word. This page will not invent a stationery template around your selfie.
Phone scans vs a real scanner
A JPEG of a paper form under kitchen light is a photograph. Shadows, curl, and keystone stay in the PDF because we never ran a deskew. Adobe Scan and Microsoft Lens do that as their product. We wrap whatever you give us. For a visa upload I still use the phone, crop tight, check that the MRZ on a passport is readable at 100% zoom, then convert. For a 40-page contract I use a feeder scanner that already exports PDF. Feeding forty JPEGs through this page one-by-one is the wrong workflow.
Search “how to convert picture to PDF on iPhone” and Apple’s own Files/Print-to-PDF dance shows up. That also produces a PDF of a picture. Ours is the same idea in a browser when you are on a laptop and the file is already on disk.
Portals that reject JPEG but accept PDF
HR ATS software, university assignment boxes, and some government forms still whitelist PDF only. A 12 MP phone JPEG is a valid photo and an invalid “document.” Wrapping it is a bureaucratic format hop, not a quality upgrade. The pixels do not get sharper. If the portal also has a 2 MB cap, convert after you resize — the bulk image resizer exists for that, not for decoration. Then run this page. If the PDF is still fat, a dedicated optimizer (or our PDF optimizer if you already have a PDF) is the next click, not a second wrap.
Going the other way — PDF pages to PNG for a slide — is PDF to image. Do not round-trip a typeset report through this page expecting to recover fonts. You would rasterize, then wrap, and the text would be a picture twice.
Color, alpha, and “print quality”
PNG logos with a cutout become a white box. That is JPEG physics, same as PNG to JPG. Screenshots of a dark UI will show a white halo if they had transparency. Flatten in an editor onto the color you actually want if white is wrong.
We are not a RIP. We do not convert to CMYK. We do not embed an ICC profile beyond what the JPEG already had. A photographer delivering gallery prints should stay in a real PDF/X workflow. A landlord who wants the leak photo in the portal can ignore that sentence.
How I run a typical upload
- Crop the receipt so the page is not 80% tablecloth.
- If the file is 8 MB and the portal is 2 MB, resize first.
- Upload here, output PDF, download.
- Open the PDF and pinch-zoom the numbers. If they are mush, the photo was mush.
No account. About two hours of storage. Send a pack that must survive longer via the homepage transfer. Rules: limits, privacy.
When I skip this converter
Anything that must be searchable. Anything that must be one file of twenty pages. Anything that needs a password (that is a different PDF tool). Anything already a PDF. A screenshot that should stay a PNG for Slack. A vector invoice that should stay SVG or a real PDF export from accounting software — photographing a screen and wrapping it is how invoices become unreadable.
iLovePDF and Smallpdf will merge, compress, and sign in one product family. They also push accounts and watermarks on free tiers. We stay a single honest wrap: image in, one-page PDF out, ads instead of a signup wall.
Page size is not magically A4
Search “convert JPG to PDF A4” and you will find tools that letterbox the photo onto 210×297 mm. We do not. The page equals the photo at 150 DPI. A 4032×3024 iPhone still is a large landscape page. A printer set to “fit to paper” will scale it down. A printer set to 100% will waste sheets or clip. If a visa site wants “passport photo on A4,” crop and pad to A4 pixels first (~1240×1754 at 150 DPI, or 2480×3508 at 300 DPI) then convert. We will not invent the white border for you.
The PDF contains a JPEG stream (DCTDecode), not a lossless PNG. That is why a PNG screenshot of text can look slightly softer — we went through JPEG. For a UI screenshot that must stay crisp, you may hate this path. Export PDF from the design tool, or keep PNG. For a photo of a leaky ceiling, JPEG-in-PDF is the correct boring file.
No /Encrypt dictionary. If the portal asked for a passworded PDF, that is a different tool after you have a PDF. Wrapping a JPEG does not add a password.
JPG to PDF, PNG to PDF, OCR
Can I drop ten photos and get one multi-page PDF?
Not here. One file, one page. Merge after if you need a packet.
Will the PDF be searchable / OCR?
No. A picture of words is not text. Run OCR in Adobe, Preview, or a scanner app.
Does a transparent PNG stay transparent in the PDF?
No. PNG to PDF on this page is a JPEG embed. Alpha flattens onto white. EXIF rotate is on for sideways iPhone photos.
