A converter that respects your files
This file converter handles the most common image and document conversions entirely in your browser. There is no upload: your files are processed on your own device, which means they stay private and the conversion starts instantly. Drag your files into the area above, pick a target format, and download the result.
What you can convert
-
Between image formats — PNG, JPG and WebP in any direction, plus AVIF, GIF and BMP as sources. Useful for shrinking photos, adding or removing transparency, or moving to a more widely supported format.
-
HEIC (iPhone photos) to JPG, PNG or PDF — Apple has used HEIC as the default photo format since iOS 11 (2017); according to Apple (WWDC 2017), files are roughly half the size of an equivalent-quality JPEG. Outside the Apple world support is patchy though — which is exactly what this conversion is for. Safari 17+ decodes natively; all other browsers load a local WebAssembly decoder from this website once. Either way your photo stays on your device.
-
SVG to PNG or JPG — render vector graphics as a raster image at a size you choose, for email, older software or upload forms that do not accept vectors.
-
PDF to images — turn each page of a PDF into a PNG, JPG or WebP picture, ready to share or embed. You pick the render resolution beforehand: 72 to 288 dpi, default 144 dpi.
-
Images to PDF — combine one or more pictures into a single, tidy PDF document.
-
Audio: MP4 to MP3 and between audio formats — pull the sound track out of a video, or convert WAV, M4A, FLAC and OGG to MP3; MP3 also goes back to WAV. You pick the bitrate: at 192 kbit/s one minute needs about 1.44 MB, while CD-quality WAV needs 10.6 MB. Where a file gets compressed twice, the pair pages say so plainly.
-
Video: MOV, MKV and WebM to MP4, plus GIF to MP4 — MOV and MKV usually already hold H.264 or HEVC; the data packets are then merely repackaged into an MP4 container, losslessly and in seconds. WebM carries VP8, VP9 or AV1 and therefore has to be re-encoded. An animated GIF is decoded frame by frame and rebuilt as video, which typically shrinks the file by a factor of 5 to 10. The tool tells you which path applies to your file before you start.
Pick any specific conversion below to open a focused page for it — for example “PDF to PNG” or “JPG to PNG” — with the right format already selected.
Why convert in the browser
Most online converters upload your files to a server, process them there and send them back. That is slower, uses your bandwidth, and means a stranger's computer briefly holds your documents. Doing the work locally avoids all of that:
- Privacy — files never leave your device.
- Speed — no upload and download round-trip.
- No limits — you are bound only by your device, not by a server quota.
Tips for the best result
- Converting to JPG produces small files but is lossy and has no transparency — use it for photos. Converting to PNG is lossless and keeps transparency — use it for graphics, logos and screenshots.
- For JPG and WebP you set the quality yourself (40–100%); 92% is a solid default, lower values save space at a visible cost. For PNG the slider is deliberately disabled — the format has no quality level.
- WebP is a good middle ground: small files with transparency, supported by all modern browsers.
- For multi-page PDFs, each page becomes its own image, and you can download them all at once as a ZIP.
- For MP3, 128 kbit/s is plenty for speech; music usually gets 192 to 320 kbit/s. A source that was already compressed does not get better from a higher bitrate.
