Convert files, without the upload.
Every conversion happens right on your device: decoded and re-encoded locally, nothing sent to a server. Pick a tool below to get started.
- Decoded on your device
- Re-encoded locally, never uploaded
- Verify it yourself in DevTools
A photo can end up in a format that just won't open where you need it: HEIC from an iPhone, JFIF from an old scanner or export tool, AVIF from a newer camera or app. These tools all solve the same problem, turning it into something that opens everywhere else, without installing anything or handing your photo to a third-party server.
HEIC to JPG
The most compatible format. Works everywhere, and keeps files small.
Combine images into a PDF, or pull images back out of one. Nothing you drop in ever leaves your browser.
Image to PDF
Combine PNG and JPG files, mixed freely, into one PDF.
SVG conversions cover more ground than a typical format swap, so they're split into three groups below: turning vector art into a normal image, tracing an image into vector art, and exporting SVG into specific formats like ICO or PDF.
SVG to image
Turn a vector graphic into a standard image file, sized however you need it.
Image to SVG
Trace an image into a scalable SVG. Logos and flat graphics come out clean. Photos and text-heavy pages don't — expect a rough, traced outline, not something you'd want to open in an editor.
PNG to SVG
Trace a PNG into a scalable SVG. Best for logos and flat graphics, not photos.
JPG to SVG
Trace a JPG into a scalable SVG. Best for logos and flat graphics, not photos.
WebP to SVG
Trace a WebP into a scalable SVG. Best for logos and flat graphics, not photos.
PDF to SVG
Trace a rendered PDF page into a scalable SVG. Best for simple, logo-like pages, not dense text.
SVG utilities
Turn an SVG into a specific format for a specific job: a favicon pack, a single PDF page, or a compact WebP for the web.

Why ConvertArena
Actually private
Nothing is uploaded, on any tool here. Open your browser's DevTools, watch the Network tab during a conversion, and see for yourself.
Instant, every time
No server queue, no upload wait. Conversion happens on your device, usually in about a second.
Growing toolset
New converters get added regularly. One place to bookmark, instead of a different site for every file type.
No hidden limits
No daily conversion cap, no forced signup after a few files, no watermark stamped on your output.
No line to wait in
Cloud converters queue your file behind everyone else's. Your device only ever works on your file.
Works on any device
Phone, laptop, or Chromebook, it works the same way on all of them. The only real requirement is a reasonably current browser.
What's next
ConvertArena is actively growing. Here's an honest look at what's currently in progress, not a fixed ship date.
Audio tools
Converting between WAV, MP3, and other common audio formats, the same way our image tools work: locally, instantly, with nothing uploaded.
Video tools
Turning short clips into GIFs and back, without a slow cloud render queue standing between you and the result.

Frequently asked questions
Yes. Every tool here is free, with no signup and no daily limit. Conversions run on your own device's processing power rather than ours, so there's no per-conversion cost for us to recoup.
No. Every tool on this site runs entirely in your browser, with no server, no database, and no upload step. Open DevTools' Network tab during a conversion and you won't see your file data going anywhere.
Right now: HEIC photos, to JPG, PNG, or PDF. More tools are on the way, covering more file types beyond images. Check the roadmap above, or the Tools menu, for the current list.
Any modern browser, on any device: Windows, Mac, Linux, iPhone, Android, or Chromebook. The only real requirement is a browser released in the last few years, since these tools rely on WebAssembly and Web Workers.
Sites like CloudConvert or FreeConvert upload your file to their servers, convert it there, then send it back. ConvertArena skips that step. Your file never leaves your device, and there's no server queue to wait behind.
No artificial limit is imposed by the tool itself. The practical ceiling is your own device's memory, since everything happens locally instead of on a remote server.
