About this tool
Make a PDF accessible reports title, language, a structure tree if one exists, the marked flag, figures, contrast, and bookmarks on long files. Pass means the marker is present. Fix available means you can type a title and a language. Needs a human means this version will not invent headings, lists, table headers, or alt text. No layout model is bundled, so reading order is not rewritten. The report is free. The page says automatic fixes are limited and points you to a screen reader and to external checkers. It does not claim PDF/UA compliance.
Make a PDF accessible stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: the report reads the file structure in this tab and does not send it to a validator.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
