Image tools
9 tools that run in your browser. Nothing to install, nothing uploaded.
Image tools that process your file entirely in your browser — it is read, transformed on a local canvas, and handed back, with no upload endpoint anywhere in the path. For this category the privacy claim is the product: you can confirm in your network panel that nothing leaves. Re-encoding also strips EXIF metadata including GPS coordinates, which is a privacy benefit worth knowing about.
- Barcode ReaderDecode a barcode from a photo, using the browser's own detector.
- Blur / Pixelate (redaction)Redact part of an image — and see why blurring is not redaction.
- EXIF Data ViewerSee every EXIF field in a photo — shooting settings and identifying data, kept apart.
- Favicon / ICO GeneratorA real multi-size favicon.ico plus the PNGs modern browsers use — no upload.
- HEIC to JPG ConverteriPhone photos into JPGs that open everywhere — converted in your browser, in batches.
- Image CompressorShrink a photo in your browser. The file is never uploaded.
- Image CropperDrag a selection, get exactly those pixels — with the ratio locked if you want.
- Image ResizerResize by pixels, percentage or preset — in your browser, never uploaded.
- EXIF / Metadata RemoverSee what your photo is telling people — then strip it, in your browser.
The file never leaves your machine
Each of these reads your image into a canvas in the page, transforms it there, and hands the result back as a download. There is no upload endpoint anywhere in the path, which for this category is the entire product rather than a side benefit — photographs are the files people are least comfortable posting to a stranger’s server and most often do anyway, because the alternative is installing software. You can verify it in about ten seconds: open the network tab, process an image, and watch nothing leave. Disconnecting from the network entirely and continuing to work is the stronger version of the same test.
What resizing and re-encoding actually cost
Two losses are worth understanding before you batch anything. Scaling down discards pixels permanently, so enlarging the result later cannot recover detail that is no longer in the file — keep the original if there is any chance you will need a larger version. And JPEG is lossy on every save, so repeatedly opening and re-exporting the same photo degrades it a little each time, even at high quality settings, in a way that shows first in flat areas like skies. Working from the original for each new output, rather than from the last export, avoids the whole problem.
Metadata is the part people forget to check
A photo from a phone typically carries EXIF metadata including the exact GPS coordinates where it was taken, the timestamp, the device model and often the serial number. Posting that image is publishing all of it, which has repeatedly turned out to matter for people sharing pictures of their home, their children’s school run or an item for sale. Re-encoding through a canvas strips this metadata as a side effect, so an image that has passed through the compressor or resizer here comes out clean; the dedicated metadata tool shows you what was there first, which is usually more convincing than being told it exists.
Frequently asked questions
Are my photos uploaded?
No. Each image is read into a canvas in the page, transformed there, and handed back as a download — there is no upload endpoint in the path. The quickest way to satisfy yourself is to open your developer tools on the network tab and process an image while watching for a request that never comes, or to disconnect from the network entirely and notice that everything still works.
Why does my image look worse after saving it a few times?
JPEG is lossy on every save, not just the first, so each open-and-re-export cycle discards a little more information — visible first as blotchiness in flat areas like skies. It is cumulative and cannot be undone. The fix is to always work from the original file for each new output rather than from your last export, and to use PNG or WebP when a format needs to survive repeated editing.
Can I make a small image larger without losing quality?
Not meaningfully. Scaling down discards pixels permanently, and scaling back up can only interpolate between what remains — the detail is gone from the file. Enlarging produces a softer or blockier result depending on the method, never the original detail. Keep the original at full size whenever there is any chance you will need a larger version later.
Does resizing remove the GPS data in my photo?
Yes, as a side effect. Re-encoding through a canvas drops EXIF metadata entirely, so an image that has passed through the resizer or compressor comes out without the coordinates, timestamp, device model and serial number a phone camera writes into it. If you want to see what was there before removing it — which is usually more persuasive than being told — use the metadata tool first.
