How to use the Image to PDF converter
- Add the images, whatever their formats; dropping a whole folder onto the page works too.
- Arrange them with the arrows; each number shows the page it will become.
- Choose a page size and margin, and whether you want one PDF or one per image.
- Press Convert to PDF and save.
How each format ends up in the file
JPG files are embedded unchanged and PNG files are stored losslessly. WebP, AVIF, HEIC, BMP, GIF and TIFF cannot sit in a PDF as they are, so they are decoded in the browser: opaque pictures become JPEG at quality 92, and pictures with transparency are kept lossless.
From an animated GIF or WebP only the first frame is used, and from a multi-page TIFF only the first page. Split a multi-page TIFF into single images first if you need every page.
One PDF or many
Leave the combine box ticked to receive a single document with every image in sequence, the usual choice for a supporting-documents upload.
Untick it and every image becomes its own one-page PDF named after the image file. That suits forms that want each certificate or receipt as a separate attachment.
Uniform pages or natural sizes
Choose A4 or Letter when the PDF goes to an office or will be printed: each image is centred and fitted, and orientation follows each image unless you force portrait or landscape.
“Same as the image” gives every page its own image’s shape, so a tall portrait shot sits next to a wide landscape page. That is fine for reading on screen but looks uneven in print.
Questions
Can I include SVG files?
No. Convert the SVG to PNG first, then add the PNG here.
Does quality drop?
JPG and PNG pages look exactly like the originals. The remaining formats go through one high-quality JPEG encode, or a lossless one when transparency is involved.
Are the images uploaded?
No. Decoding and PDF assembly happen in your browser.
