Image to PDF
Combine several photos into one PDF — for assignments, receipts, or sending scanned paperwork as a single file.
사용 방법
Drag them in or click to pick several at once. JPG, PNG, WebP, AVIF, and GIF all work, and so does iPhone HEIC. Up to 50 at a time.
Drag a thumbnail to change the page order. On mobile, press and hold first. Use ✕ to drop one.
Keep each image's own aspect ratio, or fit everything to A4 or Letter. With A4 and Letter, orientation follows each photo automatically and you can pick a margin.
Press "Create PDF" and it downloads right away. Nothing leaves your browser.
자주 묻는 질문
Does it lose quality?
No. JPG and PNG files are embedded byte for byte with no re-encoding, so quality is identical to the original. Only formats a PDF cannot hold directly (WebP, AVIF, GIF, HEIC) are converted once, at JPEG quality 92%. JPGs carrying an EXIF rotation — most iPhone photos — go through the same step, because embedding them as-is would lay them on their side in the PDF.
How is the page size decided?
With "Match each image" the page takes the exact aspect ratio of the photo, so there are no borders and nothing is cropped (the long edge is set to A4 length so it still prints sensibly). With A4 or Letter the photo is scaled to fit inside the fixed page, keeping its proportions.
What if I mix portrait and landscape photos?
Leave orientation on "Auto" and each page follows its photo — landscape photos get landscape pages. Pin it to Portrait or Landscape if you want every page the same.
Does iPhone HEIC work?
Yes. Browsers cannot read HEIC directly, so the decoder is fetched only when an HEIC file actually shows up. The first one may take a moment.
How many images can I add?
Up to 50 at a time. Large photos take memory, so it is capped. If you need more, build several PDFs and join them with the PDF Merge tool.
Are my files uploaded?
No. The PDF is built in your browser with pdf-lib. Neither the photos nor the finished PDF is sent anywhere, and both disappear when you close the page.
