Fixed size
How to Resize a PDF to a Fixed A4, A3 or Letter Page Size
Print shops, submission systems and archives often require a specific paper size, while your PDF may have come out of a web page or a scanner at an odd size. The fixed-size tool scales every page onto the target sheet.
Presets and custom sizes
The panel offers four presets — A4, A3, A5 and Letter — that fill in the dimensions for you. You can also type your own width and height; units can be pt, mm, cm or inch and they convert automatically.
| Size | Millimetres | Points (pt) |
|---|---|---|
| A4 | 210 × 297 mm | 595.28 × 841.89 |
| A3 | 297 × 420 mm | 841.89 × 1190.55 |
| A5 | 148 × 210 mm | 419.53 × 595.28 |
| Letter | 216 × 279 mm | 612 × 792 |
Values must be greater than 0 and no more than 10000. Page orientation is not forced — a landscape source page on a portrait target is scaled by the same rule described below.
The key point: it fits, it does not crop
The scale factor is min(target width ÷ source width, target height ÷ source height) — the smaller of the two, so the whole page lands inside the target sheet, then it is centred horizontally and vertically.
In practice nothing gets cropped. The trade-off is that whenever the source and target aspect ratios differ, you get white space.
| Fixed size | Fill A4 | |
|---|---|---|
| Scale factor | Minimum — fits inside | Maximum — fills the sheet |
| Crops content? | No | Yes, edges may be cut |
| Different aspect ratio | White space | Content cut off |
| Use for | Printing, submission, archives | Posters and photos printed full-bleed |
Different aspect ratios mean white space
The usual case is a landscape page going into a portrait A4. To keep everything visible the scale is limited by width, so the content sits in a narrow band with large blank areas above and below, and the type ends up small.
To avoid that, match the target orientation to your source pages. Spread files can go through Split Landscape Spreads first.
Is the text still searchable afterwards?
Yes. The tool draws each original page onto the new one at the computed scale, so vector content and the text layer survive — you can still select, search and copy the text.
Document properties do not survive. This tool rebuilds the file structure, so Title, Author, Subject and Keywords are not carried over, and the created/modified dates become the export time. If you need both a new size and those properties, resize first and add the properties afterwards with Edit Doc Properties.
How is this different from Uniform Width?
- Fixed size: every page becomes exactly the size you specify, whatever it was before.
- Uniform width: no paper size is chosen — you pick a reference page and align every page to its width.
- Fill A4: the target is A4, but the scale is the maximum, so edges may be cut.
Is the file uploaded?
No. Resizing runs in your browser and the file never leaves your device.
