About File4Edit
File4Edit is a free set of image and PDF tools (conversion, compression, resizing, merging and splitting) that run entirely in your browser, so files are never uploaded.
File4Edit is a free set of image and PDF tools — conversion, compression, resizing, merging and splitting — that run entirely in your browser, so files are never uploaded.
It is for the everyday jobs: a photo too large for an upload form, a screenshot in the wrong format, a stack of receipts that should be one PDF, a document whose pages are out of order. Most sites that do these jobs are a server with a web page in front of it. You hand over your file, a machine you cannot see processes it, and you hope the copy is deleted afterward.
File4Edit does the work on your device instead. Your browser downloads the site’s HTML, CSS and JavaScript, then reads your file from disk into the tab’s memory, decodes it in a background thread, applies your changes and hands the result back as a download. PDFs are opened with pdf.js and written with pdf-lib in the same tab. Once you have used a tool online, it keeps working offline.
Because no file is ever sent, there is nothing to delete and nothing to leak. The site itself keeps an anonymous count of page views, with no cookies and no IP addresses, and the privacy policy lists exactly what that count contains.
The design has real limits. Very large files are limited by your device’s memory rather than by a data center. Browsers cannot save every format: no browser’s built-in encoder can write AVIF, and File4Edit has no AVIF encoder of its own; Safari and iPhone cannot write WebP themselves either, so File4Edit downloads its own WebP encoder there the first time it is needed. PDF to text reads the text a document already carries, so a scan holds none for it to find; PDF OCR recognizes that text instead, and downloads a recognition engine of about four megabytes the first time it is opened. Compress PDF shrinks a document by re-encoding the images inside it, so a PDF that is all text has little to gain.
File4Edit is independently built and operated, with no advertising and no paid tier. Questions, bug reports and suggestions are welcome through the contact page.
By the numbers
How to check that nothing is uploaded
- Open the network panel Open your browser's developer tools and switch to the network panel before you process anything.
- Process a file Convert, resize or compress an image as you normally would. No request carries the file, because the work happens in the tab.
- Disconnect and keep working Turn the network off and process another file. File4Edit's service worker keeps the code each tool fetches as you use it, so a tool you have used keeps running with no connection, which a service that uploaded your file could not do.
- Check the format table on the home page The table on the home page is measured in your own browser as the page loads rather than looked up, so it shows what this browser can open and save. Reload it in a different browser and a row changes wherever that browser differs.
About File4Edit: common questions
Can anyone at File4Edit see the files I convert?
No. The tools are JavaScript running in your browser: the file is read from disk into the tab's memory and released when you close the tab. It is never sent to the site, so there is nothing on our side that could hold a copy.
Why is File4Edit free?
Because the processing happens on your own device rather than on rented servers, there is no per-file cost to recover; the site only has to deliver its pages. There is no paid tier and no account.
What are the downsides of doing this in the browser?
Three real ones. Very large images are limited by your device's memory, and above roughly 100 megapixels a browser starts refusing to allocate. Browsers cannot save every format: none can write AVIF with its own encoder, File4Edit has no AVIF encoder, and Safari needs File4Edit's own WebP encoder, which downloads the first time it is used. And nothing is remembered between visits beyond a few preferences in your own browser's local storage.
