✅ Done — your resized PDF
How it works
- Drop in your PDF — the tool reads its page count instantly, in your browser.
- Pick the target paper size (A4, US Letter, US Legal, or A5) and choose scale-to-fit (keeps proportions, centers each page) or stretch (fills the whole page edge to edge).
- Hit Resize & Download PDF — every page is rebuilt at the new size and your PDF downloads instantly.
Everyday uses
- Printing — convert an A4 document to US Letter (or the reverse) before it prints wrong.
- Job applications — make resumes and certificates a uniform paper size.
- Scans — normalize mixed-size scanned pages into one clean document.
- E-books — resize PDFs to A5 for comfortable e-reader viewing.
- Forms — fit official forms to the paper size your printer actually has.
Tip: scale-to-fit is the safe default for text — it never distorts your content. Use stretch only for full-bleed graphics.
