SquashPDF is a fast PDF compressor for iOS that shrinks PDF file size without destroying quality. Reduce a 50 MB contract to under 5 MB, fit a scanned passport into an email attachment, or hit a strict upload limit. What SquashPDF does - Compresses single or multiple PDFs in one tap - Lets you pick a target size (e.g. under 1 MB, under 5 MB, under 10 MB) instead of guessing quality levels - Batch-compresses entire folders of PDFs at once - Shows a side-by-side preview so you can verify quality before saving - Keeps a history of every compression with original vs. final size FAQ -> How much can SquashPDF reduce a PDF? Typically 60–90% for image-heavy PDFs (scans, photos). Text-only PDFs see smaller reductions because text is already efficiently encoded. -> Does SquashPDF work offline? No. Files are uploaded to our server for processing, they are not tied to your identity and are automatically deleted after two hours. -> Will compression ruin the quality of my PDF? No. Pick a target size and SquashPDF balances quality automatically. Use the side-by-side preview to compare before saving. -> Can I compress multiple PDFs at once? Yes. Batch mode compresses dozens of PDFs in one run and saves them with the original filenames. -> Is SquashPDF free? Core compression is free (daily limit of 1 pdf). SquashPDF Pro unlocks unlimited batch compression, larger files, and removes limits. -> Which file types are supported? PDF only. For best results, use SquashPDF on PDFs containing scans, photos, or screenshots — that's where the biggest savings come from. Download SquashPDF and stop fighting upload limits.
