Instructions
- Choose PDF and select Page preset.
- For Custom (mm), enter Width and Height; click Create output.
- Download the copy and inspect its page size and scaled content.
Understanding your result
An A4 preset places each page's content proportionally on an A4 page with centred padding. A wide page may leave larger margins above and below. The conversion changes page dimensions and layout, so inspect small text and drawings in the new copy.
What to do if you have a problem
If margins seem large, compare the source aspect ratio with Page preset or your custom Width and Height in millimetres. Click Create output after changing them. Check forms and annotations separately: interactive and document-level features are not copied into these rebuilt pages.
What to know before using the result
One unencrypted PDF, up to 30 MB and 500 pages. Editing invalidates digital signatures. Keep the original. Page content is embedded on new pages with proportional scaling and centred padding. Annotations, interactive forms, bookmarks, attachments and document metadata are not copied; visible annotation appearances may be omitted. Rotation and crop bounds are respected.
Files and text are held in this page while you work. Downloads are saved through your browser. Reloading or closing the tab clears the working page; a downloaded copy remains in your device's download location.
Summary
Use the resized pages after checking proportional scaling, padding and any document features that were omitted.
