Short answer
These image tools run entirely inside the web browser, using the JPEG, PNG and WebP codecs the browser already ships. Because the work is local, images are never uploaded, a typical photo is processed in well under a second, there is no file size limit imposed by the service, no account is required, and no watermark is added.
Make an image file smaller without a visible drop in quality.
Scale an image down to an exact pixel width.
Turn a sideways photo upright, or mirror it.
Turn a heavy PNG into a far smaller JPG.
Convert a JPG into a lossless PNG.
Turn a WebP saved from the web into a universally accepted JPG.
Convert WebP to PNG and keep the transparent background.
Convert images to WebP for far smaller files and faster pages.
Image editing is the part of this site that needs no engine download at all. Every browser already contains fast, hardware-assisted decoders and encoders for JPEG, PNG and WebP, so resizing a photo or converting a screenshot is a matter of milliseconds rather than the seconds a WebAssembly video encoder takes.
The trade-off is the format list. These tools read what your browser can read — JPEG, PNG, WebP, GIF and BMP — and write JPEG, PNG or WebP. Camera raw files and Apple's HEIC are not included, because no browser can decode them without a separate library.
Yes. No paid tier, no watermark, no daily limit and no account. The processing runs on your device, so there are no per-file server costs to recover.
No. Each tool decodes the file into a canvas inside your browser and re-encodes it there. You can disconnect from the internet after the page loads and the tools keep working.
JPEG, PNG, WebP, GIF and BMP — whatever your browser itself can decode. HEIC from an iPhone and camera raw files such as CR2, NEF and ARW cannot be read.
Nothing is imposed by the service. The limit is your device memory, and it is generous: a 50 megapixel photo is comfortable on a phone.
No. Re-encoding through a canvas drops EXIF entirely, so location, camera model and timestamps are removed from the output. Rotation recorded in EXIF is applied to the pixels first, so photos stay the right way up.
