Technical note: JPEG and WebP use a quality-based lossy encode in the browser. PNG is exported as PNG and does not use the lossy quality slider. When resizing is enabled, dimensions are reduced before encoding to make a larger impact on file size.
For very large images, processing time depends on your device memory, browser and image dimensions.
Built for practical compression
More control, without a complicated editor
The workflow focuses on the controls that actually change image size: quality, output format and dimensions.
◈
Format-aware output
Keep a suitable format or choose JPG, WebP or PNG when your browser supports the selected encoder.
↙
Resize while compressing
Downscaling oversized images can reduce dimensions and file bytes together, which is useful for web publishing.
Simple workflow
Compress an image in four steps
No account, complicated editor or separate desktop application is required.
Add images
Drag files into the upload area or choose multiple supported images from your device.
Set compression
Choose a preset, adjust quality, select an output format and optionally reduce width.
Compress locally
The browser processes each image and calculates the resulting file size.
Download
Preview the result, compare the sizes and save the compressed image.
Image compression guide
Choose the right balance for your image
JPEG and WebP are useful for photographs and complex images, while PNG is often preferable when transparency or lossless image data matters. WebP can be a strong web-focused option, but the best output depends on the image itself.
J
JPG
A practical choice for photographs. Lower quality usually creates smaller files, with more visible artifacts as compression becomes stronger.
W
WebP
Useful for modern websites when browser support and smaller delivery sizes are priorities. Compare the actual output rather than assuming one format always wins.
P
PNG
Useful for graphics and transparency. PNG is not a lossy format, so reducing dimensions or changing format can have a larger effect than a quality slider.
Frequently asked questions
Image Compressor FAQs
Quick answers about formats, quality, privacy and compression results.
What image formats can I compress?
The tool accepts common JPG, JPEG, PNG and WebP images. Browser support determines which image types can be decoded and re-encoded.
Are my images uploaded to a server?
This tool processes supported images in your browser. The selected image is decoded locally and the compressed result is created locally.
Can I compress multiple images at once?
Yes. You can select or drag multiple supported images and process them together using the batch workflow.
Does image compression reduce quality?
Lossy JPEG and WebP compression can reduce visual quality as quality is lowered. PNG output is generated as PNG and normally preserves the source image content without a lossy quality slider.
Can I resize an image while compressing it?
Yes. You can keep the original dimensions or choose a smaller maximum width before creating the compressed image.
Can I keep PNG transparency?
Yes. When PNG is used as the output format, the canvas preserves the alpha channel supported by the source image.
Can I convert an image to WebP while compressing it?
Yes. WebP can be selected as an output format in browsers that support WebP encoding.
Why is my compressed image sometimes larger?
Already optimized or very small images may not benefit from another encode. The tool keeps the smaller result when possible instead of claiming a size reduction that did not occur.
What quality should I use for website images?
A medium-to-high quality setting is a practical starting point for web images. The right value depends on the image, dimensions and how much visual detail you need to retain.
Does the compressor remove image metadata?
Images re-encoded through canvas are exported as new image files, so source metadata such as EXIF is generally not carried into the canvas-generated output.
