Resize PDF online

With this tool, you can instantly resize your PDF documents online for free, whether for personal or business use. It is beneficial for reducing the size of large files to conserve disk space, bandwidth, and computer memory, as well as for adjusting the paper size for printing.

Resolution Presets

Resize PDF to one of the following quality presets to adjust the image resolution throughout the document:

  • Low quality (72 dpi): Smallest file size, suitable for screen viewing and quick previews.
  • Medium quality (150 dpi): Good balance for eBooks, online sharing, and email attachments.
  • High quality (300 dpi): Full fidelity for standard printing needs.
  • Very high quality (300 dpi, full color preserved): Maximum quality for professional and large-format printing.

Paper Size Presets

You can also change the paper size of your PDF pages. Choose from standard sizes including A4, A3, Letter, Legal, and more — perfect for reformatting documents for different printers or regions.

Batch Processing

Upload and resize multiple PDF files simultaneously. All files are processed with the same settings and can be downloaded individually. This eliminates the need to purchase, download, or install any PDF editing software on your machine.

Resize PDF to Specific File Size (KB/MB)

Need your PDF to be under a certain file size? Use the low-quality (72 dpi) preset to significantly reduce file size in kilobytes. For more precise control over the output size in KB or MB, try different resolution presets or combine this tool with our PDF compressor.

Increase PDF Size and Resolution

Some upload portals and government forms require PDF files to meet a minimum file size or resolution. Use the high-quality (300 dpi) preset to increase your PDF dimensions and file size. Note that upscaling cannot restore lost image detail, but it will meet size requirements for document submissions.

Change PDF DPI

Quickly convert PDF resolution between 72 dpi, 150 dpi, and 300 dpi. This free online PDF DPI converter is ideal for adjusting image quality for screen viewing, email, eBooks, or professional printing.

Due to the trade-off between reducing PDF size and compromising some quality, we do not recommend scaling down files intended for large format printing. Additionally, this tool can increase the dimensions of a PDF, but image quality may be affected when upscaling.

All uploaded files are automatically deleted from our servers within 1 hour of upload.

Need to reduce file size without changing resolution? Try our PDF optimizer. You can also crop PDF margins to reduce page dimensions, or convert to black and white for additional size savings.
