AvePDF vs Compressify

AvePDF is a browser-based service for editing, converting, and managing PDF and other electronic documents. Its tools cover merging, splitting, compression, conversion, protection, redaction, signing, OCR, PDF/A conversion and validation, and scanning. The converter handles more than 100 formats, including raster and vector images, office and text formats, CAD, and SVG. Files can be uploaded from Google Drive, Dropbox, or a web address, with results saved to cloud storage. The Free plan costs nothing and includes 50+ document tools, 2 processing operations per 6 hours, files up to 128 MB, and up to 10 files per processing. Premium costs $45 a year, billed annually as one payment per user; it includes unlimited processing, files up to 512 MB, and up to 100 files per processing, as well as no ads, technical support, and early beta access. Free-service uploads may be retained to improve services, including to train models; Premium files are not retained. Premium subscribers also receive multiple levels of encryption.

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.
