Compressify vs iText pdfOptimizer

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.

iText pdfOptimizer is a Java and .NET add-on for iText Core that optimizes PDFs for size or speed. It can compress embedded streams, merge duplicate fonts, subset fonts, convert document color space for printing, and produce an optimization report. Image handling covers JPEG, PNG, TIFF, JBIG2, and JPEG2000, with options to scale or compress images. Presets range from High, Mid, and Low to Lossless and Custom. Developers can process multiple PDFs in a batch; if optimization makes the resulting file or image larger, the operation can be reversed. Java distribution is through iText Artifactory, while .NET distribution is through Artifactory and NuGet. The iText Suite, which includes this closed-source add-on, is offered as a 30-day trial under a commercial license. The Java installation guide requires a commercial iText Core license before installing pdfOptimizer. iText also describes an AGPL licensing option, whose terms require disclosing the full application source code. Commercial support requires a valid support subscription; AGPL users can seek community support on Stack Overflow.
