File Converter

Images and PDFs, converted on your device. Nothing is uploaded.

Drop image files here

JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, SVG · up to 30 MB each · or click to choose

This converter needs JavaScript. It runs entirely in your browser and nothing is uploaded.

Looking for video or audio? Those live on the video pages. Word, Excel and other documents need a server-side engine, so I don't offer them — CloudConvert handles those.

Each page below is the same engine set up for one job, with the details that matter for that format.

Most used


Images

PDF

Video & audio

These load a video engine the image tools do not need, so they each get their own page.

Private by design

Files are read and written on your device. The page never uploads them, so there is nothing to delete later.

No limits, no watermark

Convert as many files as you like, as often as you like. There is no queue and no daily cap.

Fast and offline-capable

Your browser does the work, so a batch finishes in seconds and keeps working without a connection.

Why I built a converter that never uploads

I got tired of sending people to converter sites that make you upload the file, wait in a queue, and hit a daily limit. So I built this one to run entirely in the browser. Your images and PDFs are processed on your own device using the browser’s image engine and a small PDF library; the page never sends them anywhere.

That has some pleasant side effects. There is no file limit worth mentioning, no watermark, no sign-up, and it works offline once the page has loaded. It also means confidential documents and personal photos are safe to convert here.

Pick a job above: convert images between JPG, PNG, and WebP; combine images into a PDF; merge several PDFs into one; split a PDF into the pages you need; or render a PDF’s pages as images. Video and audio have pages of their own further down, because they load an engine the image tools do not need. Each dedicated page below explains the details for that conversion.

Frequently asked questions

Is this really free, and what is the catch?

It is free with no catch. Because the conversion runs in your browser there is no server cost for me to recover, so there is nothing to charge for. This site is supported by the homepage itself.

Which file types can I convert?

Images in JPG, PNG, WebP, HEIC, HEIF, AVIF, GIF, BMP, and SVG can be converted to JPG, PNG, WebP, or PDF. PDFs can be merged, split, and rendered out as JPG or PNG pages. Video files can be trimmed, rewrapped as MP4, turned into a GIF, or reduced to an MP3. Documents such as Word to PDF need a server-side engine, so they are not supported here.

Are my files uploaded anywhere?

No. Nothing leaves your device. You can load the page, disconnect from the internet, and the converter still works.

Does it work on my phone?

Yes. The converter runs in the mobile versions of Safari, Chrome, Firefox, and Edge. Very large batches are limited by the memory available on the phone.

What about video, audio, or Word documents?

Video and audio now have their own pages: extract an MP3, make a GIF, trim a clip, or rewrap a MOV as MP4. They live separately because they download a 32 MB engine on first use, which the image tools should not have to carry. Document formats like DOCX to PDF still need a full office engine that is not practical to ship in a web page.
