Om dette verktøyet
One tool for every common conversion task - images, documents, audio and video - without choosing the right specific page first. Drop any file, pick the target format from the suggestions, and the converter routes it to the appropriate engine: pdf-lib for PDF work, browser canvas APIs for images, FFmpeg (WebAssembly) for media, and libheif for HEIC. Everything runs in your browser tab.
It is meant for the moment when you do not care how the conversion happens, you just want the file in a different format. If you need fine control - quality sliders, page ranges, watermark options - the per-format tools in the menu give you more knobs.
Because the work is local, there is no upload progress bar, no queue, no "please wait while the server processes your file" page. Your file is read from disk into the page, transformed in memory, and offered back as a download. Nothing in between.

The browser has to load the WebAssembly engine for the format you picked - FFmpeg for video, libheif for HEIC, and so on. Once it's loaded the engine stays cached, so the next conversion of the same type starts immediately.
Most modern devices can comfortably convert PDFs into the hundreds of pages, images up to gigapixel size, and videos up to a few hundred MB. The hard ceiling is your browser tab's memory, not a server quota.
It covers the common ones. Exotic professional formats - RAW camera files, ProRes video, lossless WAV at unusual bit depths - need the dedicated tools in the menu, which expose more options.
No. The page loads once; after that, conversions happen entirely on your device. You can verify it in the browser's network panel - your file's bytes never appear in an outgoing request.
