Free Online Image Tools
Image utilities that never upload your photo
Photos carry a lot more than pixels. Every JPEG from a phone camera can embed GPS coordinates, timestamps, device serial numbers, and the exact firmware version — data that most 'free online image tool' sites happily receive along with your file. The tools in this category work differently. Every operation — reading metadata, stripping EXIF, converting formats, resizing, compressing — runs entirely inside your browser using Canvas, exifr, and piexifjs. No file, no metadata, no thumbnail ever leaves your device. If you unplug the network after the page loads, these tools still work.

When to use these tools
Reach for these tools when you're about to post a photo online (check what EXIF you're leaking first), when a designer sends a batch of huge PNGs (compress or resize before checking them into the repo), or when your CMS demands a specific format (convert without a round-trip through some third-party service).
Frequently Asked Questions
Do these tools upload my image to a server?
No. Every tool in this category processes images in your browser using Canvas and pure-JS libraries (exifr for reading EXIF, piexifjs for stripping it). You can verify with your browser's DevTools Network tab — no request is made when you open a file.
How large an image can I open?
There is no hard-coded limit. In practice, browsers handle images up to about 100 MB smoothly. Very large panorama or DSLR RAW-like files may exhaust memory — split them or downsize first with a desktop tool.
Do the tools work offline?
Yes. Once the page has loaded, everything runs on your device. Disconnect from the internet and keep working.
Why do EXIF and other metadata matter?
EXIF metadata often contains GPS coordinates, precise timestamps, and device identifiers. Sharing an unmodified photo can reveal where you live, when you were somewhere, and which specific camera or phone was used — all without ever posting a caption.
