About Image Tools
Images are almost never the right size, format, or shape for wherever they need to go next. A camera produces a 6MB JPEG when the upload form wants 2MB. A designer sends a PNG when the site needs WebP. A profile photo needs to be square and the original is not.
This category handles the whole routine: compressing without visibly degrading quality, resizing to exact pixel dimensions or by percentage, cropping to a ratio, converting between JPEG, PNG, WebP and AVIF, and stripping the metadata your camera quietly attached.
That last one is worth pausing on. Photos taken on a phone typically embed EXIF metadata including the exact GPS coordinates where the shot was taken, the device that took it, and the timestamp. Post that image to a forum or marketplace listing and you may be publishing your home address without realising it. The EXIF tools here show you exactly what is embedded and let you strip it before the file goes anywhere.
Because processing happens on your device using the browser's own canvas and image APIs, your photos are never uploaded. That keeps personal images private, removes the upload wait entirely, and means quality is limited only by the encoder settings you choose rather than by whatever compression a server applied on the way through.
Choosing a format
JPEG suits photographs and anything with smooth gradients, but it cannot store transparency and it degrades a little every time it is re-saved. PNG is lossless and supports transparency, which makes it right for logos, screenshots and line art — and wasteful for photographs, where it often produces files several times larger than an equivalent JPEG.
WebP handles both cases well and typically lands twenty-five to thirty-five percent smaller than JPEG at matching quality. AVIF compresses harder still, often halving a JPEG, at the cost of slower encoding. Both are supported by every current browser. For anything going on a website, WebP is usually the pragmatic default; keep JPEG or PNG when a file must open in older software or be accepted by a system you do not control.
Resizing without wrecking the image
Scaling an image down discards pixels and generally looks fine. Scaling up invents them, and no amount of processing recovers detail that was never captured — an enlarged image looks soft or artificial because the extra pixels are guesses. Always start from the largest original you have rather than enlarging something already reduced.
Keep the aspect ratio locked unless you specifically want distortion. If an image must fill a fixed shape that does not match its proportions, crop it rather than stretching it. Cropping loses content at the edges, which the viewer never notices; stretching makes faces and circles visibly wrong, which they notice immediately.
Frequently asked questions
Are my photos uploaded anywhere?
No. Images are read into your browser and processed on your device using the canvas and image APIs built into the browser itself. Nothing is transmitted to a server or stored. This matters especially for personal photos, which often carry location metadata and are among the most sensitive files people handle casually.
Will compressing an image visibly reduce its quality?
Usually not at moderate settings. Compression works by discarding detail the eye is least sensitive to, and most photographs can lose sixty to eighty percent of their file size with no difference visible at normal viewing size. It is lossy and irreversible, though, so keep the original if the image matters — and check the result at full zoom before replacing anything.
What is EXIF data and should I remove it?
EXIF is metadata your camera embeds in the file: the device model, exposure settings, timestamp, and on most phones the precise GPS coordinates where the photo was taken. Remove it before posting images publicly, particularly anything taken at home. Keep it if you rely on it for organising a photo library or need the capture details.
Can I process several images at once?
Yes — the bulk image resizer handles a whole batch in one pass, and applies the same settings across every file. Since processing happens on your device, a large batch is limited only by your device's memory and speed rather than by an upload queue.
