How Image Compress Tools works
Image Compress Tools is a free image compressor and WebP converter that runs in a modern browser. Image files stay on the device throughout validation, processing, preview, and download.
- Inputs
- JPG/JPEG, PNG, WebP, AVIF, static GIF, and standard BMP.
- Outputs
- WebP, PNG, and JPG.
- Batch size
- Up to 50 images and 250 MB of source data.
- Image size
- Up to 40 megapixels and 16,384 pixels per side.
The local processing pipeline
Validate the source file
The browser checks the file signature and dimensions before decoding. Unsupported or animated files are rejected rather than silently converted to a single frame.
Resize and encode in the browser
The decoded pixels are optionally resized and then encoded as WebP, PNG, or JPG. A newly encoded file does not copy embedded EXIF or XMP metadata. If a same-format, same-dimension result would be larger, the application can instead return the source file byte-for-byte, including its original metadata.
Download the generated result
The output is made available as an individual download or a batch ZIP. The application does not retain source or output image files after the browser session.
What to expect
Compression results depend on the source image, its dimensions, the selected output format, and the quality setting. An already optimized image can stay the same size or become larger, so the interface reports the actual result instead of promising a fixed percentage reduction.
The application requires JavaScript for image processing. Its public explanations, FAQs, metadata, and structured data are rendered as HTML so search engines and assistive technologies can read them without operating the compressor.
