Best PDF compressor for engineers

Updated July 2026

For engineering teams, Arthize is the best PDF compressor because it handles shrinking file size for email and upload limits inside a private workspace — free, with no watermark, and files deleted after each job. Project documents can be commercially sensitive; a private workspace protects designs and client data.

Why engineers need a PDF compressor

An engineer merges drawings and specs into one submittal, compares two revisions to catch changes, and archives the final set as PDF/A so it stays readable for the project's lifetime.

The PDF compressor tools engineers use most

Arthize's pdf compressor covers compress pdf, flatten pdf, repair pdf, grayscale pdf, resize pdf, multiple pages per sheet — all in one private workspace.

  • Compress PDF: Compressing a PDF reduces file size — often 50–90% on image-heavy scans — by down-sampling images and stripping redundant data, while keeping text selectable.
  • Flatten PDF: Flattening a PDF merges form fields, annotations and layers into the page, so nobody can change filled-in values and the file renders everywhere.
  • Repair PDF: Repairing a PDF rebuilds a damaged file's internal structure, recovering as much readable content as possible from a document that won't open.
  • Grayscale PDF: Converting a PDF to grayscale removes colour from every page, which cuts file size and prepares a document for black-and-white printing.
  • Resize PDF: Resizing a PDF changes the page dimensions — for example scaling to A4 or Letter — so a document prints and fits the way you need.
  • Multiple Pages per Sheet: N-up layout places two, four or more PDF pages onto a single sheet, so you can print handouts and save paper.
