What is Lilypad?
Lilypad is a free set of image and PDF tools that run entirely in your web browser. It converts HEIC, WebP, AVIF, PNG and JPG images, turns images into a PDF and PDF pages into images, and compresses, resizes, crops, rotates and removes hidden metadata from photos. It also makes QR codes and barcodes, and reads them from images or your camera. Your files are processed on your own device and are never uploaded. There’s no sign-up, no watermark and no limit on the number of files.
Is Lilypad the right tool for you?
A good fit for
- Private or confidential files, like ID scans, contracts, medical letters or family photos: nothing is uploaded, so nobody else ever has a copy.
- Lots of files at once, like a whole iPhone album: convert them in one go and download a single ZIP.
- Quick jobs on any device, phones included, without installing an app or creating an account.
Not the best choice for
- Saving as HEIC: browsers can’t write HEIC files, so HEIC photos always come out as another format.
- Real photo editing, like straightening, retouching or removing a background: use a photo editor.
- Automated conversions on a server: use a command-line tool such as ImageMagick or libvips.
Why use Lilypad
100% private
Files are processed right in your browser. Nothing is ever uploaded to a server.
Batch processing
Add hundreds of files at once and download them all in a single ZIP or PDF.
Fast & free
Uses every core of your CPU. No sign-up, no watermarks, no file limits.
Which format should I choose?
- JPG
- Opens on every phone, computer, and website. Pick this if you are not sure.
- PNG
- Lossless, so no quality is lost. File sizes are 3–5× larger than JPG.
- WebP
- Around 30% smaller than JPG at the same quality. Supported by all modern browsers.
- AVIF
- The smallest files, often half the size of JPG. Newer, so a few older apps cannot open it.
Frequently asked questions
What is a HEIC file?
HEIC (High Efficiency Image Container) is the photo format iPhones and iPads use by default since iOS 11. It keeps photos small, but many Windows PCs, Android phones, websites and apps cannot open it.
Are my photos uploaded anywhere?
No. Everything runs inside your web browser using WebAssembly. Your photos never leave your device, and we never see them.
Is there a limit on how many photos I can convert?
No. Add as many as you like. Very large batches are processed a few at a time so your device does not run out of memory.
Does converting reduce quality?
At the default settings the difference is invisible. Choose PNG for a lossless copy, or raise the quality slider for JPG, WebP and AVIF.
What happens to photo metadata like location?
Converted images do not include the original metadata (EXIF), so GPS location, camera details and timestamps are removed. That makes them safer to share publicly.
Why is AVIF slower?
AVIF squeezes images much smaller, which takes more computation. Expect a few seconds per photo.
Can I use it on my phone?
Yes. It works in any modern browser on Android, iPhone, Windows, Mac, Linux and ChromeOS.
