True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.
LaunchEdit text in place, sign, redact, fill forms, and reorganize PDF files in your browser — all on your device. No upload, no subscription.
Drop two versions of a contract or drawing set. Moved notes read as moves, changed values light up digit by digit, and hidden text is named.
LaunchSide-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Drop a Gerber ZIP, an ODB++ .tgz or an IPC-2581 .xml and inspect every layer — compare revisions, snap-to-pad measure, run DRC and preview the board in 3D.
LaunchOpen Gerber, Excellon, ODB++ and IPC-2581 PCB files. Inspect layers, measure traces, run DRC, export to PNG / SVG / DXF.
Open a .step / .stp part and it measures itself: volume, thinnest wall, draft and undercuts on load, and a hole list with a BOM in one click. Measure, section, export STL.
LaunchOpen a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Compress, merge, split, convert, and manipulate PDF files.
Resize, compress, convert, and transform images.
Convert, compress, and cut audio and video — MP3, WAV, MP4, WebM, Opus — all in your browser, nothing uploads.
Simulate a canning process down to its F0 sterilizing value.
Encrypt files, share encrypted notes as links, and read passport IDs and Windows event logs.
Analyze packet captures, move files between devices, and console into network gear — nothing uploads.
Scan receipts into an expense ledger — your receipts and spending stay on your device.
View, measure, and repair CAD and 3D files — STEP, STL, OBJ, PLY, GLB, 3MF, DXF, and Gerber — right in your browser. Nothing uploads.
Pull the soundtrack out of a clip with Extract Audio from Video, shrink a recording with Compress Audio, or switch formats with the Audio Converter. Video to GIF turns a short clip into an animated GIF, and the Video Compressor fits a video under an email or chat size limit.
Extract the audio from an MP4, MOV, WebM or MKV video and save it as MP3 or WAV, or FLAC, M4A, OGG or Opus where the browser can encode them. Batch several videos into one ZIP.
Compress MP3, WAV, M4A, FLAC, OGG, AAC, and Opus files to a target bitrate or WhatsApp's 16 MB limit. Batch mode included. Runs entirely in your browser.
Convert audio between MP3, WAV, and Opus. Batch mode included. Runs 100% in your browser — nothing uploads.
Convert a video clip to an animated GIF in your browser. Trim, set fps, and choose width. No upload, no watermark, no ezgif account needed.
Read and edit ID3 tags on MP3 files — title, artist, album, year, genre, track, comment, and album art. Runs entirely in your browser. Nothing uploads.
Convert MKV, MOV, or WebM to MP4 in your browser — fast lossless copy when possible, re-encode for maximum compatibility. No upload, no watermark.
Shrink MP4, WebM, MOV, or MKV in your browser — get a smaller file under your email, Slack, or Discord upload limit.
Remove the sound from a video and keep the picture exactly as it was. The video stream is copied, not re-encoded, so it is instant and lossless. MP4, MOV, M4V, WebM, MKV and TS.
Live translated subtitles for any browser tab's audio in desktop Chrome: speech becomes subtitles as it plays, translated on the device, with a transcript to save as SRT, VTT or text.
Try clearing filters or adjusting your search — most categories have dozens of tools once you widen the net.
Convert, compress, and repackage audio and video in your browser: MP3, WAV, FLAC, M4A, OGG, and Opus on the audio side, and MP4, WebM, MOV, and MKV on the video side. Turn a WhatsApp .opus voice note into an MP3 that email clients accept, pull the audio out of a screen recording, shrink a clip under a Discord or WhatsApp size cap by working the bitrate back from your target size, strip the sound from a video for a silent loop, edit the tags and album art on an MP3, or turn a clip into an animated GIF. Batch mode converts a set of files at once and downloads the results as a ZIP. Encoding runs on your device, so voice notes, lecture recordings, and home videos stay on your machine, and there is no queue or rate limit. Format coverage matches what your browser can decode and encode: the common modern set, not legacy codecs like WMA, WMV, or FLV.
Audio: MP3, WAV, FLAC, M4A/AAC, OGG, and Opus in and out. Video: MP4, WebM, MOV, and MKV in; MP4 (H.264/H.265) and WebM (VP9/AV1) out. AVI files do not open. Coverage matches what your browser can decode and encode via WebCodecs — the common modern set, not legacy formats like WMA, WMV, or FLV.
Yes. Remove Audio from Video takes files up to 4 GB, because it copies the video instead of re-encoding it and writes the result to browser storage. The video converter, video compressor and Extract Audio take files up to 500 MB; Video to GIF, the Audio Converter, and Compress Audio up to 200 MB, and the Audio Tag Editor up to 100 MB. Processing happens on your device, so large files take longer on a slower machine. Encoding runs in a Web Worker via WebCodecs and the mediabunny engine, off the main thread so the page stays responsive.
Some — the video compressor targets a file size (e.g. Discord 8MB, WhatsApp 16MB) by back-solving the bitrate, or you pick a quality level. Audio compression picks a codec and bitrate. Defaults aim for near-original quality at a fraction of the size; lower the target to shrink further, trading size against quality.
No. Every audio and video tool runs entirely in your browser — files never touch a server, nothing is logged, and results download straight to your device. Privacy-sensitive recordings (voice memos, legal calls, home videos) stay local throughout.
