Why people use Felx

Private by design

PDF and image tools do their work inside your browser. Your documents are not uploaded to Felx servers, so there is nothing for us to store or delete.

Fast on slow internet

Because files are not sent anywhere, a 20 MB PDF is ready as soon as your phone has processed it — even on a weak mobile connection.

Free, without the catch

No account and no watermark on your files. The site is kept free by advertising, which never sits inside a tool.

Frequently asked questions

Is Felx really free?

Yes. Every tool is free to use, with no account, no trial and no watermark on your files. Felx is supported by advertising.

Are my files uploaded anywhere?

No. The PDF and image tools run inside your web browser, so your documents and photos stay on your phone or computer. Only the video downloaders use our server, because they need to fetch the video from the link you paste.

How do I reduce a photo to 20 KB or 50 KB for an exam form?

Open Compress Image to KB, choose your photo, pick 20 KB or 50 KB (or type any size) and, if the form asks for it, the pixel size. Felx finds the best quality that fits under the limit and gives you a JPG to upload.

Does Felx work on mobile phones?

Yes. All tools work in Chrome, Safari and other modern browsers on Android and iPhone. Very large PDFs are faster on a computer.

Can I edit a PDF for free without a watermark?

Yes. The Felx PDF Editor lets you change and add text, sign, highlight, add images and rearrange pages, and the downloaded PDF has no watermark.
