Check what the recipient accepts

A PDF is useful when a recipient wants one attachment with a clear page order, such as a short walkthrough or a record of interface states. ScreenReady puts one image on each page. It does not merge existing PDF files, recognise text with OCR, or create selectable text from screenshots.

If a form requires searchable text, use a document workflow that produces accessible text rather than assuming an image PDF will satisfy that requirement. Keep a written description alongside screenshots when the information needs to be accessible to a screen-reader user.

Prepare safe source images

Choose still PNG, JPEG or WebP files. Remove irrelevant screenshots and put the remaining images in a logical sequence. A useful example is an initial settings screen, a changed option and the resulting confirmation. Repeated screens make the document longer without explaining more.

Use the editor to crop distractions and add explanations. Use permanent redaction for private details, apply all redactions, and export the safe result. The PDF workspace does not inherit another tool's edits: add those exported images rather than the original files.

Arrange the pages

  1. Open Image to PDF and choose or drop the images. Processing happens locally in your browser, without an image upload to a conversion server.
  2. Check the numbered thumbnails. Use Move up and Move down or drag rows to set page order.
  3. Select A4 or US Letter, portrait or landscape, and margins from 0 to 50 mm. The settings apply to the document.
  4. Generate the PDF, then download and open it in a PDF viewer. Each selected image becomes one page.

Make text readable on the page

Images are centred and fitted inside the margins while keeping their proportions. A wide screenshot on a portrait page may have substantial white space and small text. Landscape orientation or cropping unnecessary source edges can help. Reducing margins increases the space available, but check the result if it will be printed. Transparent areas become white.

Freshly rendered RGB pixels use lossless compression. Large images may be reduced to at most 200 dpi and 4 megapixels per page to control memory use. Lossless compression does not restore detail lost through downscaling or earlier JPEG compression. Inspect the smallest important text in the saved document.

Review limits, privacy and delivery

Collections accept up to 25 images within the displayed source, pixel and memory budgets. PDF generation requires a browser with CompressionStream support. A large collection may fail on a device with limited memory; try fewer or smaller images. A failed or cancelled generation does not offer a partial PDF.

The output embeds rendered image pixels rather than the original files or their source EXIF, GPS and XMP metadata. Visible details still remain unless you removed them. Check page count, order, private content and readability before sharing. Download before closing the page, because the workspace does not save your project.
