Everything we can do with your files. Most of it runs right in your browser.
Images
- Image converterin your browserConvert images between JPG, PNG, WebP, AVIF and HEIC. Resize and strip EXIF along the way.
- Resize imagein your browserChange the dimensions of a photo or picture. Fits within your numbers without enlarging.
- Compress imagein your browserMake a photo lighter — down to a size limit or by quality. Handy when a form refuses a large file.
- Crop imagein your browserCut a photo to a ratio — square for an avatar, 16:9 for a cover. Nothing gets scaled down.
- Rotate imagein your browserTurn a photo by 90, 180 or 270 degrees, or mirror it. Sideways phone shots get fixed.
- Remove EXIF and locationin your browserStrip the camera model, the date and — most importantly — the coordinates from a photo. JPEG and PNG are cleaned byte by byte, so the picture itself is not touched.
- Colour palette from an imagein your browserPull the main colours out of a picture and get ready-made CSS variables. Runs in your browser: the photo never leaves it.
- Photo for a websiteStrips the geotag and camera data, fits the long side into 1600 pixels and encodes WebP. One step instead of three settings.
Audio
- Audio converterConvert audio between MP3, AAC, OPUS, FLAC, WAV and OGG. Pick a bitrate, drop it to mono, change the sample rate.
- Extract audio from videoPull the soundtrack out of a video file. When the track can be lifted as is, nothing is re-encoded and nothing is lost.
- Trim audioCut a fragment out of a recording by timecodes. By default the stream is copied, so the cut costs no quality.
- Normalize loudnessEven out loudness to the EBU R128 broadcast standard, in two passes — so the recording does not breathe.
- Merge audioJoin several recordings into one, in the order you picked. Matching files are joined without re-encoding — instantly and with no quality lost.
- Trim silenceCut the silence at the start and the end of a recording. Pauses inside are left alone — in speech they carry meaning.
- Edit audio tagsChange the title, artist and album. The audio itself is copied untouched, so nothing is lost and it takes no time.
Video
- Convert videoTurn a video into MP4, WebM or MKV. MP4 plays everywhere, WebM is for the web, MKV is what you usually need to open somewhere else.
- Crop video frameCut the frame to the ratio you need — vertical for a feed, square for a post. Nothing is stretched: only the excess is removed.
- Compress videoFit a recording into a given number of megabytes — to send by email or messenger. We work out the bitrate for your limit and encode in two passes to hit it.
- Resize videoConvert a recording to 1080p, 720p, 480p or 360p. Width follows the original proportions, so nothing gets stretched. Upscaling is refused: it adds no detail and only inflates the file.
- Trim videoCut out a fragment by timecodes. The stream is copied without re-encoding, so it is fast and lossless. If the cut cannot land on a keyframe, we re-encode and say so.
- Remove audio from videoDrop the sound track. The picture is copied as is — no quality loss and no waiting.
- Video to GIFBuild a GIF from a fragment. The palette is generated for your specific video in a separate pass — without that you get noise instead of a picture.
- Add subtitles to videoBurn subtitles into the picture or attach them as a track. Burned-in subtitles show everywhere, even where nobody turns them on; attached ones the viewer can switch off, and the picture is not re-encoded.
- Video thumbnailGrab a frame for a cover or preview. Exactly one frame is decoded, so an hour of video costs no more than a minute.
- Video for a messengerSqueezes the recording to 24 megabytes — a size that passes both mail and messengers. The bitrate is computed for your file; the audio stays.
- Video for shortsTurn a horizontal recording into something a vertical feed accepts: crop the frame to the centre and bring it to 1080 pixels tall.
- Merge PDFin your browserJoin several PDF files into one, in the order you picked. Nothing is re-rendered: pages are copied as they are.
- Split PDFin your browserPull pages out of a PDF — a range, a few ranges, or every page as its own file.
- Rotate and delete PDF pagesTurn pages that were scanned sideways and drop the ones you do not need — in one pass over the document.
- Images to PDFin your browserTurn photos and scans into one PDF, in the order you picked. HEIC from an iPhone works too.
- Compress PDFMake a PDF lighter by re-encoding the images inside it. If the result is not meaningfully smaller, you get the original back — untouched.
- PDF to imagesTurn PDF pages into JPG or PNG — one image per page. Handy when the document has to be shown where PDF is not opened.
- PDF to textPull the text out of a document. Works where text exists: a scan is a picture, and we do not recognise it.
- Unlock PDFRemove the password from a document you can already open. You type the password — we never guess it.
- Password-protect PDFLock a document with a password before sending it. Without the password it will not open anywhere.
Documents
- Documents to PDFWord, Excel and PowerPoint to PDF so the layout survives the trip. Takes docx, xlsx, pptx as well as older doc, xls, ppt and open odt, ods, odp.
- Document for sendingWord, Excel or a deck becomes a PDF and is compressed right away — so the attachment fits through mail and the layout survives the trip.
Archives
- Create a ZIPin your browserPut several files into one archive so you can send them as a single attachment. Packed in the browser — the files never reach a server.
- Unzip filesin your browserGet the files out of an archive. Paths like "../.." are defused, and an archive that expands out of all proportion to its size is refused.

Data
Utilities
- File checksumin your browserWork out the MD5, SHA-1, SHA-256 or SHA-512 of a file to check that what you downloaded is what was published. The file never leaves your device.
- File to base64 and backin your browserEncode a file as base64 — to paste an image straight into CSS, say — or decode a base64 string back into a file. The direction is worked out for you.
