Compress Image guide
How to compress JPG, PNG, and WebP images
Reduce image file size directly in your browser while keeping the original pixel dimensions. Add one or more images, choose a quality level, then download the smaller results.
Add your images
Select JPG, PNG, or WebP files from your device or drag them into the upload area.
Choose image quality
Adjust the quality control to balance smaller output files against visual detail, especially for JPG and WebP images.
Compare and download
Fylento shows the original and compressed sizes, then lets you download files individually or together as a ZIP.
How compression differs by image format
Fylento keeps the same output format as the source image, but JPG, PNG, and WebP do not compress in exactly the same way.
JPG
JPG uses lossy compression, so lowering quality can reduce file size significantly while introducing more visible compression artifacts.
WebP
WebP also responds well to quality adjustments and can often produce compact image files while maintaining good visual quality.
PNG
PNG is normally encoded losslessly by the browser, so the quality slider may have little or no effect compared with JPG or WebP. Savings depend on how efficiently the original PNG was encoded.
Compress images privately in your browser
Fylento performs the image re-encoding on your device. Your selected images do not need to be uploaded to a remote image-compression service.
Original dimensions are preserved
Compression changes the encoded image data, not the width and height in pixels. Use Resize Image when you also want to reduce dimensions.
Same image format
JPG remains JPG, PNG remains PNG, and WebP remains WebP after compression.
Avoids larger results
If re-encoding would create a file that is the same size or larger than the original, Fylento keeps the original file instead.
Batch compression
Compress multiple images in one session and download all results together in a ZIP when working with a batch.
When smaller image files are useful
Smaller images can upload faster, use less storage, and be easier to share when a website or service has file-size limits.
Compress Image FAQ
Does image compression change the dimensions?
No. The current Compress Image tool keeps the original pixel width and height. It changes the image encoding to try to reduce file size.
Does Fylento upload my images?
No. Compression happens locally in your browser for this tool.
Why did my image not get smaller?
Some images are already efficiently compressed. If Fylento's re-encoded version is not smaller, the tool keeps the original instead of replacing it with a larger file.
Does the quality slider affect PNG?
Usually not in the same way as JPG or WebP. Browser PNG output is generally lossless, so the quality setting may be ignored and file-size savings depend mostly on re-encoding efficiency.
Can I compress several images at once?
Yes. Add multiple supported images, compress the batch, then download each result separately or all results together as a ZIP.
