Reduce file size while keeping quality high. Same format by default, no downscaling unless you ask. Runs in your browser.
Reduces file size while keeping quality high. It defaults to your original format and does not change dimensions unless you turn on resizing.
JPG and WebP are lossy formats, so no compressor can guarantee zero quality loss. PNG output stays lossless but is usually larger. The panel reports the achieved size so you can decide.
The image is processed on your device. Nothing is uploaded, and re-encoding strips EXIF and GPS metadata.
This tool reduces image file size with as little visible quality loss as practical, in your browser. By default it keeps your original format and does not downscale, so the image stays as close to the original as possible.
It is honest about the limits: JPG and WebP are lossy, so some detail is always traded for size. There is no zero-loss guarantee and no quality metric here; instead the result panel reports the achieved size so you can judge the trade-off yourself.
Targets a generous size and keeps your format by default, so quality stays close to the original.
Dimensions are left unchanged unless you turn on resizing yourself.
States plainly that lossy formats cannot be zero-loss, and reports the achieved size instead of claiming perfection.
All processing happens in your browser; nothing is uploaded to a server.
Trim file size while keeping images looking sharp.
Reduce weight without an obvious drop in clarity.
Store smaller copies that still look close to the originals.
Choose PNG output to avoid lossy artifacts when transparency or flat colour matters.
Not for JPG or WebP, which are lossy formats. No compressor can guarantee zero quality loss for them. Choose PNG output if you need lossless, though the file will usually be larger.
No, not unless you turn on resizing. By default the image keeps its full dimensions to preserve quality.
No. The image is processed in your browser, so it never leaves your device.
The result panel shows the original and output size and the percentage saved. You can open the downloaded image to compare it with the original.
This tool does not compute a visual-difference metric such as SSIM or PSNR, so it does not claim a specific quality level. It reports file size and lets you compare the images yourself.
