How to Convert WebP to PDF Free: 4 Easy Methods

By Picovert Team2026-05-214 min read

WebP is the modern web image format — compact, fast to load, and widely used for screenshots, product images, and web graphics. But when you need to share these images via email, submit them for print, or package multiple screenshots into a single document, PDF is the right format. It opens on every device, combines multiple images into one file, and preserves the layout exactly. Here are four free methods to convert WebP to PDF.

Why Convert WebP to PDF?

  • Email and sharing — Not every email client or recipient can open a WebP file directly. A PDF opens instantly on any device without a special viewer.
  • Print compatibility — Many print services and document workflows require PDF. Converting WebP ensures consistent page size, margins, and quality at print.
  • Combining multiple screenshots — If you have a series of WebP screenshots (bug reports, design reviews, tutorials), bundling them into a single PDF is far easier to share and review than a folder of image files.
  • Portfolio and presentation — A PDF portfolio of web images is professional and universally readable, whether you send it to a client or upload it to a platform.

Method 1: Online Converter (Fastest — No Software)

Use Picovert's Image to PDF converter — it works entirely in your browser. Files are never sent to a server, no account is needed, and there are no file size limits beyond your device memory.

  1. Open the Image to PDF tool.
  2. Drag and drop your WebP file — or multiple WebP files at once. JPG, PNG, AVIF, and other formats are also supported.
  3. Reorder pages by dragging the thumbnails if needed.
  4. Click "Convert to PDF" and download your PDF instantly.

Each WebP becomes one page in the PDF. The tool auto-detects portrait vs. landscape orientation and scales the image to fill the A4 page while preserving the aspect ratio. For batch conversions — combining dozens of screenshots into one PDF — this is the fastest cross-platform option with no software to install.

Method 2: Windows — Convert via Browser Print

Windows does not have a built-in WebP-to-PDF converter, but you can use Chrome or Edge (which natively support WebP) as a workaround:

  1. Drag your WebP file directly into a Chrome or Edge browser window to open it.
  2. Press Ctrl+P to open the print dialog.
  3. In the "Destination" dropdown, select Save as PDF.
  4. Adjust page size (A4 or Letter) and margins if needed. Set margins to "None" for a borderless result.
  5. Click Save, choose a filename and location, and the PDF is created.

Note: each WebP file becomes one page in the PDF. To combine multiple WebP files, use Method 1 (Picovert) or Method 4 (ImageMagick) instead.

Method 3: Mac — Print to PDF

macOS has native PDF export baked into the print system — no third-party software required:

  1. Open the WebP file in Preview (double-click the file) or Safari (drag into the browser window).
  2. Press Cmd+P to open the Print dialog.
  3. In the bottom-left corner, click the PDF dropdown button.
  4. Select Save as PDF, enter a filename and choose a save location, then click Save.

To convert multiple WebP files into a single PDF on Mac: open all of them together in Preview (select all files in Finder, right-click → Open With → Preview). In Preview, go to View → Thumbnails to see all images as pages, then choose File → Print → PDF → Save as PDF to export the entire set as one document.

Method 4: ImageMagick (Batch Command Line)

For automated or large-batch conversions, ImageMagick is the best free command-line option. It runs on Mac, Windows, and Linux.

  1. Install on Mac: brew install imagemagick
    Install on Windows: download from imagemagick.org and run the installer.
  2. Single file: convert input.webp output.pdf
  3. Multiple WebP files into one PDF: convert *.webp combined.pdf
  4. With quality control: convert -quality 85 *.webp combined.pdf

The convert *.webp combined.pdf command processes all WebP files in the current folder alphabetically and places each on a separate page. The -quality 85 flag controls the JPEG compression applied to images embedded in the PDF — values between 85 and 95 are recommended for web images and screenshots.

A Note on WebP Quality and PDF Output

WebP is already a compressed format — converting it to PDF embeds the image data as-is. The quality of the PDF output depends on the original WebP:

  • Lossless WebP source — If quality is critical (diagrams, text-heavy screenshots, design mockups), use a lossless WebP as the input. The embedded image will retain every pixel.
  • Lossy WebP source — Lossy WebP files still look excellent for web viewing and general print at standard resolutions. Converting a lossy WebP to PDF does not add further compression — the PDF simply wraps the existing image data.
  • Large PDFs — If the resulting PDF is too large, you can compress the WebP images first before converting, or use the -quality 75 flag with ImageMagick to reduce the embedded quality.
