# ToolBench (mytoolsbench.com) > ToolBench is a free collection of browser-based image tools: convert, compress, resize, crop and watermark images. All processing happens locally in the user's browser using the Canvas API. Files are never uploaded to a server, there is no sign-up, and there is no file size or file count limit. Key facts: - Privacy: images never leave the user's device. The page keeps working offline once loaded. - Free to use, no account, no watermark added to outputs. - Supported output formats: JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO and PDF. HEIC input is supported. - When converting transparent images to JPG, transparent areas are filled with white (not black). - Formats that browsers cannot write (EPS, PSD, SVG, TGA) are intentionally not offered, because they would require server uploads. ## Guides -
