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.
Black out text and images in a PDF and remove them for real: each redacted page is redrawn as an image, so the covered text cannot be copied or extracted.
Yes. Each redacted page is redrawn as an image, and the original page is deleted from the saved file along with its text, comments, and form values. Text you redact is also removed from the document title, metadata and bookmark names, whether a search found it or a drawn box covers it. Under a box that means its phrases and its whole words of four letters or more; the result lists any shorter word it left. The saved file is then searched for what you redacted. Short or plain single words under a box cannot be searched for without matching the file's own structure, so the result lists those as not checked. A box over a scanned page has no text to compare, so the result says to check the title yourself. Attached files and hidden application data are removed from the saved file, because they can hold a copy of what you redacted, and the result says how many files went.
Yes. You can search for specific words or phrases and redact all occurrences at once, including in comments and form fields. Each match is boxed to its own letters, not the whole line.
Yes. Find personal data scans page text, comments, form fields (hidden ones too) and link targets for US Social Security numbers, email addresses, phone numbers, card numbers (checked with the Luhn checksum) and IBANs (checked with their checksum). Uncheck any false positives, then mark the rest. Scanned pages have no text to search; run OCR first or draw boxes on them.
Yes. In a browser with WebMCP the page offers redact_pdf and find_pdf_redactions, and headless browsers can call window.loft.tools.invoke('redact-pdf'). The agent gets a report of what was redacted where, the result of the file check, a receipt with the SHA-256 of both files, and the redacted PDF.
Pages without redactions are kept as they were. A page that holds a redaction is replaced by an image of itself, so its text is no longer selectable and its links, form fields and annotations are dropped. Bookmarks and links that point at a redacted page open its image. Attached files are not kept, and a form field that no page shows is removed.
