Save, share, and find it again Save the result to Files or send it through the share sheet. Saved results remain available in History for previewing, sharing, renaming, or deleting later. Process your PDFs locally Compression runs locally without uploading your documents to a processing server. No app account is required. Choose the access that fits your needs Free access includes advertising and two successful compressions per day. Cancelled or failed attempts and results without a meaningful size reduction do not use your allowance. Previewing, saving, and sharing an existing result remain available without using another compression. Optional Pro access removes advertising and the daily compression limit. The same compression quality options are available with free and Pro access. Before you compress Compression converts each page into an image within the output PDF. Visual quality may decrease, and text in the compressed copy will no longer be selectable or searchable. Some PDFs may not become smaller, and a specific output size is not guaranteed. PDF Compressor lets you use the app at no cost. However, premium access may be available as an optional in-app upgrade.
