Compressify vs PDFOptim

Compressify is a file-compression service for images and PDFs, available on the web, Android, iOS, and as an extension. It supports batch processing and image resizing, with listed formats including JPG, JPEG, PNG, SVG, WebP, HEIC, GIF, BMP, and TIFF. Compressify says it can reduce JPG, PNG, SVG, WebP, and PDF files by up to 90%. The image compressor handles JPEG, PNG, and WebP and analyzes each image to choose an encoding strategy. PDF compression needs no settings, supports batches, and is free five times a day. A Figma plugin bulk-compresses exports and can merge selected frames into one PDF. A WordPress plugin compresses new uploads, bulk-optimizes existing media, and optionally converts to WebP; routine processing runs through WordPress image editors locally. Free costs nothing, billed Free Forever, with 60 Image Exports per month and limited features. Pro costs $4.99 a month.

PDFOptim provides browser tools to compress, merge, split, rotate, and reorder PDF files, alongside native apps for macOS, iOS, iPad, and Windows. Browser processing uses JavaScript and WebAssembly without uploading files to PDFOptim servers, and the tools work offline after the page has loaded; initial loading and license verification need internet access. Compression offers Web, Standard, Print, and Custom settings, and can reduce PDF size by up to 90%. Compress Only mode strips metadata and compresses internal streams without re-rendering software-created PDFs, preserving selectable text. Multiple PDFs can be batch-compressed, while downloading all results as a ZIP requires Pro. The free plan allows three operations per day on files up to 25 MB. Pro Monthly costs $4.99 a month and includes unlimited operations, files up to 200 MB, and batch ZIP downloads. Lifetime costs $19, paid once, with the same operation and file limits, batch ZIP downloads, future tools, and priority email support. The native apps process documents locally; a 30-day money-back guarantee is also listed.
