图片转 PDF

Convert image to PDF in your browser

This image to PDF converter turns photos, scans and screenshots into a proper PDF document. Every picture gets its own page, sized and centered the way you choose, and the whole set downloads as one file.

It's handy when a form only accepts PDF, when you've photographed a multi-page document with your phone, or when you want to send a batch of receipts or notes as a single attachment instead of a dozen loose images.

Page options explained

Images are never cropped or stretched. They're scaled to fit inside the margin while keeping their shape, so a photo that doesn't match the page proportions leaves some white space.

What people use an image to PDF converter for

Documents photographed on a phone

A lease, a signed form or a few pages of handwritten notes, shot with the phone camera, become a single PDF that reads in order. It looks far more professional to the person receiving it than six separate JPGs in a chat.

ID cards, certificates and mark sheets

Many application portals ask for documents as PDF even when you only have a photo. Put the front and back of an ID card on two pages, or each certificate on its own page, and upload one file instead of several.

Receipts and invoices

Expense systems and accountants usually prefer one PDF per claim. Snap the receipts, drop them in, and send a tidy document with one receipt per page.

Screenshots and slides

Choose landscape for wide screenshots or exported slides. With the margin at 0, each picture fills its page, which makes the PDF easy to scroll through on a laptop.

Image to PDF 200KB: keeping the file small

Upload portals often ask for a PDF under 200 KB or 500 KB. Because JPEG and PNG files go into the PDF without being re-encoded, the PDF ends up about as big as the images you add. So the trick is to make the images small before converting:

• Resize first. A phone photo is 4000 pixels wide or more. For a document page, 1200 to 1600 pixels is plenty. Use Resize Image.
• Compress with a target. In Compress Image, set a target per image. For a 200 KB PDF with two pages, aim for about 90 KB each.
• Use JPG, not PNG or HEIC. Other formats are stored as lossless PNG inside the PDF, which is far larger for photos. Convert with HEIC to JPG or PNG to JPG first.
• Already made the PDF? Run it through Compress PDF with the Screen preset.

Supported image formats

You can convert JPG, JPEG, PNG, WEBP, HEIC, HEIF, AVIF, TIFF, GIF and BMP images. JPEG and PNG are placed into the PDF directly. All other formats are decoded in the browser first and stored as PNG, so transparency in a PNG or WEBP logo shows up as white on the page.

Animated GIFs contribute their first frame. Multi-page TIFF files contribute their first page. If you only need a single format, the dedicated JPG to PDF converter does the same job for JPEG photos.

Photographing documents for a cleaner PDF

• Lay the page flat on a dark surface in daylight, with no flash, so the paper stands out and there's no glare.
• Hold the phone directly above the page rather than at an angle, so the text isn't skewed.
• Crop away the table and your fingers before converting; the crop option in Resize Image works well for this.
• Shoot every page in the same orientation, then choose portrait in the page options.

Private and free

Your pictures are read from your device and the PDF is assembled in your browser. Nothing is uploaded, stored or logged, which matters when the images are IDs, medical letters or bank documents. There's no account, no watermark and no limit on how many PDFs you create. Each image can be up to 250 MB, with up to 20 images per PDF. To add the result to other PDFs, use Merge PDF.
