Picmu
Built around real file formats
From PNG, JPG, WebP, and AVIF to MP4, WebM, and WAV, Picmu works with the formats your browser can preview, process, and export.

Three focused toolsets
Picmu covers image work, careful browser video tools, and practical audio editing without dumping everything into one overloaded screen.
Compress, resize, crop, remove metadata, prepare for print, and batch export without hiding the job behind generic tabs.
Check browser support for conversion, compression, trim, crop, mute, metadata cleanup, audio extraction, and frame capture before you commit.
Inspect waveform data, trim clips, merge files, adjust gain, normalize, convert, remove metadata, and batch export while keeping playback, decode, and export support clearly separate.
Capture still frames from video, extract audio from video, and move between image, video, and audio tools when the job changes.
Why Picmu is easy to trust
Straightforward tools, clear notes, and behavior that matches what the browser can actually do.
Core image processing, video inspection, and audio handling stay in the browser. Files do not get pushed into a remote media queue.
Format support, print readiness, and browser limits are explained plainly.
Picmu grows through hubs and dedicated tools, not one bloated page trying to do everything.
Tools
Pick the right tool from the start
Picmu gives image, video, and audio tasks their own tools, format-pair pages, and browser notes written in plain language.
Image workflow hub
Image tools
Open exact pairs like PNG to JPG, GIF to PNG, or TIFF to WebP when the format decision is already made.
Compression, resize, crop, metadata cleanup, print prep, and batch export each have a dedicated tool.
Files stay on your device while the page previews, processes, and exports the result.
Video workflow hub
Video tools
Conversion, compression, resize, rotate, trim, crop, mute, metadata cleanup, audio extraction, and frame capture each have a dedicated page.
You see what this browser can actually decode, record, and export before you start relying on it.
Even with partial video support, you can still inspect metadata, preview the file, and save a still frame.
Audio workflow hub
Audio tools
Conversion, compression, trim, merge, gain, normalization, speed changes, metadata cleanup, waveform inspection, and batch export each have a dedicated page.
Audio pages keep playback, decode, waveform analysis, and export support separate, so you can see what works before processing.
When compressed export is limited, the page still gives you file facts, trim planning, and the best local output available.

FAQ
Frequently asked questions
Picmu explains what stays local, which image, video, and audio tools work in the current browser, and where export, transparency, print, codec, or waveform limits still apply.
No. Picmu is built around local browser processing, so your files stay on your device instead of being sent to a remote media pipeline.
