Every iPhone photo you take is in HEIC format. Try to share it with someone on Windows or upload it to a form that only accepts JPG -- and you're stuck.
Most online converters upload your photos to their servers. That means your private photos (with GPS location data in the EXIF metadata) are sitting on someone else's server.
We built a better way.
HEIC to JPG Converter -- 100% Private, No Upload
The HEIC to JPG Converter runs entirely in your browser using WebAssembly. Your photos never leave your device.
- Drag and drop HEIC/HEIF files
- Batch convert multiple photos at once
- Quality slider (1-100) to control file size
- Output to JPG, PNG, or WebP
- EXIF metadata toggle (strip GPS data for privacy)
- Download individually or as a ZIP file
- Copy converted image directly to clipboard
This is the converter privacy-conscious users have been asking for on Reddit and Hacker News.
Image Format Converter -- Every Format, One Tool
Need to convert PNG to WebP? JPG to PNG? BMP to anything? Instead of finding a different tool for each format pair, we built a Universal Image Format Converter.
- Supports: JPG, PNG, WebP, BMP, GIF, TIFF, SVG, ICO
- Batch convert multiple images
- Resize options: custom dimensions or percentage scale
- Quality slider for lossy formats
- File size comparison (see how much you saved)
- Download all as ZIP
Same privacy promise -- everything stays in your browser.
Days in a Year Calculator -- More Useful Than You'd Think
Google tells you "365 days." But how many of those are weekdays? How many are left in the current year? Which day of the week does the year start on?
The Days in a Year Calculator answers all of these:
- Weekday vs weekend breakdown for any year
- Remaining days counter with progress bar
- Leap year checker
- Days between any two dates
- "How many days have I been alive?" calculator
- Day-of-week count table (52 Mondays, 52 Tuesdays...)
Ounces to Liters Converter -- Because Recipes Don't Convert Themselves
Americans use fluid ounces. Everyone else uses liters. The Ounces to Liters Converter handles both:
- Bidirectional: oz to liters AND liters to oz
- US vs Imperial fluid ounces toggle (they're different!)
- Also shows: mL, cups, tablespoons, gallons, pints, quarts
- Quick reference table for common amounts
- Batch converter for multiple values
