## What is Sonic Tools?

Sonic Tools puts more than 50 PDF, image and video tools in one free app. No ads, no account, no watermarks on your files, and no limits on how much you use it.

Pick a tool, pick a file, and you're done. Every tool shows a quick animation of what it does, so you always know which one you need.

PDF TOOLS
• Compress PDF: shrink scans and photos so files are small enough to email
• Scan to PDF: point your camera at paper and get a clean, straight PDF
• Merge, split, organize, rotate, crop, remove pages and extract pages
• Sign: draw your signature and place it on any page
• Fill forms: type into the fields of a PDF form
• Watermark and page numbers: stamp DRAFT or your own words, number every page
• Redact: black out private details so they're gone for good, not just covered
• Protect and unlock: add a password, or take off one you know
• Repair a PDF that won't open, and compare two versions to see what changed
• Edit the title, author and other hidden details
• Convert Word, Excel and PowerPoint to PDF, photos to PDF, and PDF pages to images
• Extract images: save the pictures inside a PDF at full quality

IMAGE TOOLS
• Compress photos so they're smaller but still sharp
• Resize, crop, rotate and flip
• Convert HEIC to JPG, PNG or WebP
• Remove background: lift the subject out of any photo
• Blur faces before you share a picture
• Image to text: copy the words in a photo, receipt or screenshot
• Remove location: strip GPS and camera details from photos
• Watermark photos with your name or handle

VIDEO TOOLS
• Compress video so it's small enough to send anywhere
• Trim, mute, rotate, change speed, merge clips and resize for square, story or widescreen
• Convert MOV to MP4 and MP4 to MOV
• Make compatible: turn HEVC video into H.264 so it plays everywhere
• Video to audio: save the sound as M4A, WAV or AIFF
• Video to GIF and GIF to video
• Video to photos: save any frame, or a set of frames, as pictures
• Photos to video: turn your photos into a slideshow

PRIVATE BY DESIGN
Your files are worked on right on your iPhone or iPad and never leave it. The one exception is Word, Excel and PowerPoint to PDF: laying out Office files exactly needs a full office engine, so that tool sends the file to our converter over a secure connection, and it's deleted as soon as the PDF comes back. The app tells you this before you convert.

BUILT FOR EVERY SCREEN
Sonic Tools works on iPhone, iPad and iPhone Duo, and follows your device's light or dark setting. Results go straight to Files or Photos, or share them anywhere.
