Images to PDF

JPG, JPEG, PNG, BMP, GIF, TIFF, PNM, PGM, PBM, PPM, PAM, JXR, JPX, JP2, PSD, SVG, HEIC, HEIF, and WebP. You can mix formats in one batch, and each image becomes its own page in a single images_to_pdf.pdf file.

High Quality embeds your images as they are, with no resizing or re-encoding. Medium re-encodes each image as a JPEG at 75% quality and caps the longest side at 2500 pixels, and Low uses 50% quality with a 1500 pixel cap, which gives much smaller files for email.

Only at High Quality, where files are embedded untouched. Medium and Low convert every image to JPEG, which has no alpha channel, so transparent areas are flattened rather than kept.

Pages follow the order of the file list, which is the order you selected or dropped the images. To change it, remove an image with the trash icon and add it again with Add More Files so it goes to the end.

Not in this tool. Each page takes the dimensions of its image, so a tall phone photo produces a tall page and a landscape scan a wide one. If you need uniform paper sizes afterward, run the result through Fix Page Size.

No. HEIC and HEIF files are decoded in the browser and turned into PNG before they're embedded, and WebP is handled the same way. This happens automatically and doesn't need an extra step.

No. Decoding, compression, and PDF assembly all run in your browser, so the images never leave your device. Large batches of full-resolution photos take longer and use more memory on your machine because of that.

JPG to PDF gives the same result with a simpler interface, and there are dedicated PNG, HEIC, WebP, and TIFF converters as well. This tool is the one to reach for when your files are in mixed or less common formats such as PSD, JXR, or PNM.
