Make every file fit.
Free, fast, and private tools that adapt your images and documents to any size or format limit — without ever leaving your device.
Why File Size Tools?
Upload limits are everywhere — job portals that cap a résumé photo at 500 KB, government forms that reject a PDF over 2 MB, marketplaces that demand square thumbnails. File Size Tools exists to make those limits effortless to meet. Each tool runs entirely inside your web browser using the Canvas and PDF APIs, so your personal documents and photos are never sent to a server, stored, or seen by anyone but you.
Private by design
There is no account, no upload, and no tracking of your files. When you close the tab, nothing remains. This matters most for the sensitive documents people resize every day — passports, tax forms, medical records, and IDs.
