Image tools where the image never leaves your computer
Ten tools for resizing, cropping, converting, generating favicons and reading EXIF. Everything happens in the browser, so there is no upload queue, no daily limit, and no copy of your photo sitting on somebody's server.
The usual bargain with a free image site is that you hand over the file. It gets uploaded, processed on a server, and you download the result — and the original stays there under terms nobody reads. For a holiday snap that is merely untidy. For a passport scan, a signed document or an unpublished product shot, it is a genuine problem.
These tools use the browser's own canvas and file APIs, so the picture is read from disk, processed in memory and saved back without a single byte crossing the network. That is also why there is no queue and no size cap beyond what your device can hold.
No tool matches that.
Resize & Crop
- Image Resizer
Resize an image to exact pixels or a percentage, with an option to keep it locked to the original aspect ratio.
- Image Cropper
Crop an image to a custom box or a common preset ratio like square, 16:9, or 4:3.
- Aspect Ratio Calculator
Find the missing width or height that keeps an image or video at a target aspect ratio.
Convert
- Image Format Converter
Convert an image between PNG, JPEG, and WebP instantly, with a quality slider for lossy formats.
- Image to Base64 Converter
Convert an image to a Base64 data URI, or paste a data URI to preview and download the image.
Generators
- Favicon Generator
Turn any image into a full set of favicon sizes, ready to download and drop into your site.
- CSS Gradient Generator
Design a linear or radial CSS gradient visually and copy the ready-to-use CSS code.
- Image Color Picker
Click anywhere on an uploaded image to read its exact color as HEX, RGB, and HSL.
Creative
- Meme Generator
Add bold top and bottom captions to any image and download the finished meme.
Analyze
- EXIF Viewer
See a photo's hidden EXIF metadata — camera model, date taken, exposure settings, and GPS location if present.

Resize, convert, or create?
For fitting an image to a requirement, the resizer keeps aspect ratio by default and shows the resulting file size before you save, which is what you actually need when a form demands under 2 MB. The cropper and the aspect ratio calculator handle the reverse problem: a fixed shape you must fill.
For format changes, the converter moves between JPEG, PNG and WebP. WebP is the one worth knowing about: for most photographs it is meaningfully smaller than JPEG at the same visible quality, which is free page speed on a site you run.
For making things, the favicon generator produces the icon sizes a site needs, the CSS gradient generator writes the rule for you, and the colour picker pulls exact hex values out of an image rather than approximating by eye.
The EXIF viewer is a privacy tool
Photos carry hidden metadata: camera, timestamp, and often the GPS coordinates where the picture was taken. Most people posting a photo of something for sale have no idea it may include their home address to within a few metres.
The EXIF viewer shows exactly what a file is carrying, so you can check before you publish. Since it runs locally, checking a sensitive image does not require handing it to anyone.
Common questions
Are my images uploaded anywhere?
No. Every tool reads the file directly from your device and processes it in the browser. Nothing is transmitted, nothing is stored, and there is no server-side copy to delete.
Is there a file size or daily limit?
No daily limit at all. The practical size ceiling is your device's memory, since the image is held in RAM while it is worked on. Very large files are slower on a phone than on a laptop, which is the only real constraint.
Does resizing lose quality?
Making an image smaller is generally clean. Making it larger cannot invent detail that was never captured, so an enlarged image looks softer — that is a property of the pixels, not of the tool. Save as PNG or WebP if you are editing repeatedly, since JPEG loses a little more each time it is re-encoded.
Should I use WebP or JPEG?
WebP for anything on the web: smaller files at the same visible quality, and every current browser supports it. JPEG remains the safer choice for something being sent to a print shop, an older application, or anyone whose software you cannot predict.
Can I strip location data from a photo?
The EXIF viewer shows you what metadata is present, including GPS coordinates. Re-saving an image through the resizer or format converter produces a new file from raw pixels, which does not carry the original metadata with it.
