Append photos or scans to an existing PDF. The original pages stay exactly as they are.

Audio Trimmer

Video to MP3
Turn the sound of a video into an MP3. Drop the file, pick a bitrate, done — all on your device.
Crop an image
Drag a frame over your picture, keep a fixed ratio if you need one, and straighten a tilted horizon. Everything happens on your device.
Rotate a video
Turn a video by a quarter, put it the right way up or mirror it. The turn is written into the picture itself, so every player shows it correctly.
Crop a video
Cut the picture, not the length. Drag a frame over the first still or pick a ratio — 9:16 turns a wide clip into a portrait one.
Grab a still from a video
Pick a moment and save it as a picture, or pull one frame every few seconds to get an overview of the whole clip. Nothing is uploaded.
PDF to text
Pull the words out of a PDF and save them as a plain text file. Lines and paragraphs are rebuilt from the layout, so it reads like text and not like a list of fragments.

PDF to HTML
Turn selectable PDF text into a clean HTML document locally.

Watermark a PDF
Lay text or a logo over every page — or only the ones you pick. Set how faint it is, where it sits and how large. Nothing is uploaded.
Crop PDF margins
Trim wide white edges so the page fills your screen or your print. The text is untouched — only the visible frame moves.
Combine images
Put several pictures into one: side by side, stacked or in a grid. Set the gap, the background and whether uneven sizes get matched up.
SVG to PNG
Turn a vector drawing into pixels at any size you need. An SVG has no fixed size, so you pick the width. The file is drawn as an image, never run as a document.
PNG to SVG
Trace a logo or drawing into a real SVG made of editable paths. Nothing is uploaded.
PDF to images
Turn PDF pages into PNG, JPG or WebP files. Pick the pages and the resolution — 150 dpi reads well on screen, 300 is for print.
Normalise audio volume
Bring quiet recordings up to a usable level — and a whole batch to the same level, so you stop reaching for the volume knob between files.
See and remove photo metadata
Photos carry more than the picture: camera, date and often the exact spot where you stood. Look at what is in there, then strip it out before you share.
Change video speed
Make a clip faster or slower, from quarter speed to four times. The sound follows along so picture and audio stay together.
Organise PDF pages
Reorder, rotate, delete and duplicate the pages of a PDF. Drag the thumbnails or use the buttons — and take a step back whenever you need to.
Sign a PDF
Draw your signature with a finger or a mouse, place it where it belongs and fill in the blanks. Everything happens on your device.
