Convert WebP to PDF: what to know

Images saved from websites increasingly arrive as WebP, and WebP is not something a PDF can contain, a print shop can open, or most document portals will accept. This page decodes the WebP files in your browser and writes them into a PDF — one page per image, in the order you choose — without uploading anything.

How to convert WebP to PDF

Add the WebP files above, arrange them with the arrows (or Sort by name), choose a page size and click Create PDF. Combine into one PDF puts every image into a single document; switch it off to get one PDF per image. Up to 20 files, 20 MB each, per batch.

How WebP is stored in the PDF

PDF viewers understand JPG and PNG-style image data, not WebP, so every WebP is decoded first. Images with transparency are stored losslessly as PNG-style pixels, so a logo with a transparent background keeps it and shows the page's white behind it. Opaque images are stored as JPG at quality 92, which is visually identical to the source at normal viewing sizes. Animated WebP files contribute their first frame only.

Because the image is rebuilt from pixels, no metadata from the WebP file travels into the PDF, and any EXIF orientation is applied first.

Choosing a page layout

Fit to image gives each page the exact pixel size of the image — the right choice for a set of product shots or a portfolio that will only be viewed on screen. A4 or US Letter with Auto orientation gives a printable document where each image is scaled to fit inside the page (never cropped); add a 10 or 20 mm margin if the pages will be printed and bound. Every image on a fixed page is centred, and small images are scaled up to fill the page width or height.

Size and quality

WebP files are small, and the JPG pages made from them are usually two to three times larger — that is the cost of a format every PDF viewer can read. If the document must stay under a limit, Reduce file size lowers the JPG quality to 80 and caps the long side at 2480 pixels, which is still sharp on paper. For a lossless document of graphics and text, leave Reduce off; transparent images stay lossless automatically.

Questions about WebP to PDF

Are my images uploaded?
No. The WebP files are decoded and the PDF is written in your browser.
Does the PDF keep transparency?
Yes, for transparent WebP images; they are stored losslessly and show the page background behind them.
What about animated WebP?
The first frame becomes the page; animation cannot be kept in a PDF.
Can I put many WebP files in one PDF?
Yes — up to 20 per batch, in the order you choose.

How to make a PDF from images

  1. Add up to 20 images — JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, SVG, ICO or TIFF. They stay in your browser.
  2. Put them in order with the arrows (or Sort by name), then choose Fit to image for screen use or A4 / US Letter for a printable document.
  3. Click Create PDF and download the file — or send it to PDF to Image, or keep one PDF per image by turning off Combine.

JPG and PNG files are embedded exactly as they are, so nothing is re-compressed unless you turn on Reduce file size. HEIC, WebP, AVIF, GIF, BMP, SVG, ICO and TIFF are decoded first and stored as JPG (or PNG when transparent).

Useful details

Are my images uploaded?

No. The PDF is written in your browser and the images never leave your device. Keep the tab open until you download or send the result — reloading clears the batch. Website hosting and performance measurement are described in our Privacy notice.

Which images can I use?

JPG, PNG, WebP, HEIC/HEIF (iPhone photos), AVIF, GIF, BMP, SVG, ICO and TIFF, up to 20 files, 20 MB each and 100 MB per batch, at most 40 megapixels each. Animated files contribute their first frame. PDFs are not accepted here — use PDF to Image for those.

Does converting lower the quality?

Not for JPG and PNG: their bytes are placed in the PDF unchanged. Other formats are decoded and stored as JPG at quality 92 (or lossless PNG when transparent), which is visually identical. Reduce file size is the only setting that trades quality for size, and it is off by default.

How do I keep the PDF small?

Turn on Reduce file size: every image becomes a JPG at quality 80 with the long side capped at 2480 pixels — about 300 dpi on A4 — which typically shrinks phone photos six to eight times. For an exact budget, compress the images first with a target size and send the results here.

What do Fit to image, A4 and US Letter mean?

Fit to image makes each page exactly the size of its image, so nothing is scaled or padded. A4 and US Letter make standard printable pages; each image is scaled to fit inside the margins and centred. Auto orientation turns wide images onto landscape pages.

Why did my sideways phone photo come out upright?

Phones store many photos rotated with an orientation flag. Toolkitta reads the flag and rotates those photos before placing them, so the PDF shows them the way your phone does. The file details say how many photos were rotated.

Is metadata copied into the PDF?

No. EXIF data such as camera settings and GPS location is not written into the document; only the picture is. The PDF's own properties list Toolkitta as the producer and the creation time.

How do I continue in another tool?

Use Send to under the finished PDF to open PDF to Image with it loaded, or start from the compressor, cropper or converter and use Send to → Image to PDF from their results.
