ONELESS · IMAGE LIGHT
When a folder contains a mixture of photographs, screenshots, and transparent graphics, the first useful step is often simply to make one image lighter. Image Compressor accepts JPEG, PNG, and still WebP, recognizes the actual format, and keeps that format in the result. The controls adapt to the picture: JPEG and WebP use a quality setting, while PNG uses lossless pixel encoding. The comparison and byte counts stay in the same places.

UNDERSTAND THE RESULT
A JPEG remains JPEG, a PNG remains PNG, and a WebP remains WebP. This compressor does not silently convert a transparent image to an opaque format or change its extension to make it appear smaller. Use a dedicated converter when you want to change formats.
JPEG and WebP quality trades detail for storage through the browser encoder. PNG uses adaptive filtering and DEFLATE without a quality slider or palette reduction. Its decoded 8-bit pixels and alpha are preserved in the new encoding.
Original and Result bars show actual file sizes after encoding. The preview divider lets you compare corresponding details at the same dimensions. When the result is larger, the interface says so and leaves Download original available.
HOW TO USE IT
EVERYDAY USES
Use one workspace for individual files from different formats. This release processes one image at a time; it does not silently promise a batch download or combine results.
Reduce JPEG or WebP quality gradually while watching texture and lettering. A quality setting is not a guaranteed percentage of retained visual information.
Let a PNG use its own lossless path. It retains alpha and dimensions, while the size comparison makes clear whether optimization actually helped this particular image.
YOUR IMAGE, YOUR DEVICE
The selected image is read and processed in this browser. This tool does not upload the file to a server or save it in browser storage. Choosing another file or leaving the tool releases its working images. Downloaded copies remain wherever your browser saves them.
Every change starts from the original image in memory. Export creates a new raster file; original EXIF, camera information, and embedded profile metadata are not copied. Browser decoding and color management can affect the result, so keep your original for archival work.
This release handles one file at a time, up to 25 MB, 16 megapixels, and 16,384 pixels on either side. Animated images are rejected rather than flattened to one frame. Browser encoding support can vary. A failed export shows an error and never leaves an outdated result ready to download. Read the site privacy policy for the surrounding website.
File sizes and limits use decimal units: 1 KB = 1,000 bytes and 1 MB = 1,000,000 bytes. Rounded labels are for readability; target checks compare exact bytes.
KEEP IT NEARBY
Bookmark this page with Ctrl + D on Windows or Command + D on a Mac. To make a desktop shortcut, use your browser’s shortcut or Add to Home Screen option when available. The shortcut opens the tool page; it does not include your image or settings.
Download a PNG or ICO if your device lets you customize shortcut icons.
QUESTIONS, ANSWERED
Those tools accept one known format and explain its specific options. This tool detects any of the three supported formats and selects the corresponding controls and encoding path in one workspace.
No. Displayed dimensions are preserved. Use Resize Image to KB when smaller dimensions are acceptable for meeting a byte limit.
The browser quality setting is not a lossless guarantee for JPEG or WebP. PNG uses lossless encoding of decoded pixels, with no quality control.
PNG and WebP results preserve transparency. JPEG sources are opaque. This format-preserving workflow does not add a white background to a transparent source.
No. Already optimized images may grow when encoded again. The tool reports a larger result accurately and offers the original file as an alternative.
Animated files are rejected, because this editor creates still raster images. Original metadata is not copied into the new output, and browser decoding and color management apply.
