How to verify an edit changed only what you asked
Most PDF editors quietly change more than you asked: fonts get swapped, lines shift, images are recompressed. MythosPDF is built to change only what you edit, and the Compare button lets you verify it for yourself.

- 1Make your edits in the editor.
- 2Press Compare in the top bar.
- 3Review the marked areas on each page; they should match exactly the edits you made.
- 4Close Compare and press Export PDF.

Open PDF editorTips
- ✓When a longer edit reflows a paragraph, the lines below it move and show as changed too. That's expected.
- ✓For files edited elsewhere, use Compare PDF with the original and the edited file.
Questions people ask
+Why is a whole paragraph marked when I changed one word?
If your word made a line longer, the paragraph rewrapped, so later lines moved.
+Is my original kept?
Yes. Your upload is never modified. Every edit is a new revision.
