What Resize PDF Pages to A4 or Letter actually does to your file
Content is scaled to fit the selected page size while keeping its aspect ratio, so nothing is cut off - instead you get even margins where the proportions differ, and a small page is scaled up as readily as a large one is shrunk. Because it is a scale rather than a re-layout, type that was set at 10pt ends up smaller or larger than the new page expects, which is what you want for a faithful copy and not what you want for a printable form. A document that mixes page sizes collapses to one size for every sheet. The result stays vector, so text remains selectable, and processing is local to the browser.
Resize PDF Pages to A4 or Letter FAQ
What does Resize PDF Pages to A4 or Letter do?
Fit PDF pages to A4, Letter, A3, or Legal paper sizes without uploading the document.
Which files work with Resize PDF Pages to A4 or Letter?
This category commonly supports PDF and exported JPG or PNG pages. Use the accepted file types shown in the uploader, because support varies by browser and by the engine behind each tool.
Will numbering restart or overwrite existing page numbers?
Numbering is drawn on top of what is already there, so an existing folio stays visible underneath. Preview a middle page and the final page before you export.
Will my original file be changed?
No. The work is done on a copy in this tab by pdf.js and pdf-lib, and the result arrives as a separate download, so your original is still there if you need it.
How is my file processed?
It is not uploaded. The processing is done locally by pdf.js and pdf-lib, so the practical ceiling is your device's memory and the limit shown beside the uploader - no queue, no account, no copy on a server.
Does resizing compress the PDF?
No. The primary operation changes page dimensions and scales content. File size may change as a side effect, but this is not a target-size compressor.
