A free online file converter and PDF editor for every format
Tools Root is a free online file converter, PDF editor, image compressor, and document conversion platform built around one idea: every everyday file task, converting, compressing, merging, or editing, should be fast, free, and private, without installing desktop software or creating an account. Whether you need a PDF merger, a PDF compressor, a JPG to PNG converter, or an MP4 video compressor, this free online tool works the same way in every browser, on Windows, Mac, Linux, Android, or iPhone. No install, no signup, no watermark, and no per-file paywall.
What sets this file converter apart from most free online conversion websites is where the actual conversion happens. Every one of the 70 tools listed on this site, PDF tools, image tools, an image format converter, document converters, audio tools, an audio format converter, video tools, a video format converter, and archive tools, runs entirely inside your own browser tab using JavaScript and WebAssembly. Your PDF, photo, Word document, MP3, or video file is read, processed, and written back out locally on your own device. It is never uploaded to a remote server, which is exactly why this online file converter is both genuinely private and noticeably faster than upload-then-download alternatives: there is no upload wait, no server queue, and no file sitting on someone else's storage after you close the tab.
Free PDF tools: merge, compress, split, and convert PDF online
The PDF tools collection covers the full range of everyday PDF work: a free PDF merger to combine multiple PDF files into one document, a PDF splitter to pull pages out into their own file, a PDF compressor to shrink an oversized PDF for email, and dedicated tools to rotate PDF pages, add a PDF watermark, password protect a PDF, or run OCR on a scanned PDF to make it searchable. Need to move between PDF and Office formats? The document tools category has a free Word to PDF converter, a PDF to Word converter, plus Excel and PowerPoint conversions in both directions.
Image converter and photo editing tools: JPG, PNG, WEBP, HEIC, and more
The image converter handles every common image format pair: a JPG to PNG converter, a PNG to JPG converter, a HEIC to JPG converter for iPhone photos, and WEBP, AVIF, GIF, BMP, TIFF, and SVG conversions, alongside an all-in-one converter for any format combination. Once a photo is in the right format, the image tools category picks up from there with an image compressor to shrink file size, image resizing, image cropping, a background remover built on a genuine machine-learning segmentation model, and image watermarking and metadata inspection tools.
Audio and video converters: compress, trim, and convert MP4, MP3, and more
For audio and video, the same locally-run engine (a real FFmpeg build compiled to WebAssembly) powers a video compressor, a video format converter covering MP4, MOV, AVI, MKV, and animated GIF, plus video trimming, video resizing, and video watermarking. The audio converter covers every common pairing, including an MP4 to MP3 converter for pulling audio out of a video file, alongside audio trimming, merging, and loudness normalization in the audio tools category. Rounding things out, the archive tools category creates and extracts ZIP, 7Z, TAR, and GZ archives, and can extract RAR files as well.
Why choose a browser-based file converter over desktop software
Traditional file conversion means picking one of two flawed options: install a separate desktop app for every format you work with, or upload your file to an unfamiliar website and hope it's deleted afterward. A browser-based converter that genuinely processes files on-device solves both problems at once: there's nothing to install, nothing to update, and no file ever leaves your computer to be converted somewhere else. That also means these tools keep working offline once a page has loaded, and scale to as many files or as large a batch as your own device's memory allows, rather than a shared server's usage quota. For a closer look at picking the right tool for a specific job, the JPG vs PNG vs WEBP guide and PDF file size guide on the blog cover two of the most common format and compression questions in more detail.
Handling large files without an upload limit slowing you down
Because every conversion, compression, and edit happens inside your own browser tab rather than on a remote server, this file converter is not bound by the strict upload caps that many free online tools enforce to manage server load and bandwidth costs. A large video file, a high-resolution photo batch, or a lengthy scanned PDF can be processed the same way a small file is, since the only real constraint is your own device's available memory rather than a fixed server-side ceiling. The video compressor and video converter in particular are sized generously for this reason, since video files are typically the largest everyday file type people need to convert or shrink down for sharing.
A free file converter that works on phones and tablets, not just desktop
Every tool on this site is built to work the same way on a phone or tablet browser as it does on a desktop computer, which matters most for the tools people actually reach for on mobile: converting a HEIC photo from an iPhone to JPG before sending it to someone with an Android phone, signing a PDF form with a finger on a touchscreen using the PDF signature tool, or quickly compressing a photo taken moments earlier so it fits an email attachment limit. Since nothing needs installing from an app store and no account needs creating, there is no meaningful difference between reaching for one of these tools on a laptop at a desk or on a phone between other tasks, a genuine advantage over desktop-only software that simply is not available away from that one installed computer.
How this free online converter compares to paid software and other conversion sites
Desktop suites like Adobe Acrobat or dedicated video editing software offer deep, professional-grade feature sets, but they cost money, require installation, and are tied to one device. Many other free online converters offer similar convenience to this site on the surface, but route your file through a server to perform the conversion, meaning the file is uploaded before you ever see a result and is subject to whatever retention or deletion policy that particular site happens to have. This collection of tools aims to sit in a genuinely different spot: professional-enough results for the overwhelming majority of everyday PDF, image, document, audio, and video tasks, with none of the cost, installation, or upload-and-hope-it's- deleted tradeoffs either alternative asks for.
