Email and uploads
Check the recipient’s file-size limit. Create a delivery copy while keeping the original for future editing.
Websites and product pages
Smaller files can load faster, but confirm that the site accepts your chosen format.
Small text and thin lines
Compression artifacts show quickly around sharp edges. Inspect at full size and increase quality if necessary.
Faces and textured photographs
Compare hair, leaves, skin detail, and gradients. Use the lowest quality that still looks suitable for the intended display.
Scope and limitations
Know what this tool does and does not do
1A compressed image is not guaranteed to be smaller than an already optimized original.
2Format conversion can discard camera or location metadata.
3Compression does not prepare physical print dimensions.
4No fixed percentage reduction is guaranteed; photographs, screenshots, flat graphics, and already-compressed files behave differently.
5The current compressor does not promise lossless output, metadata preservation, animation preservation, or exact color-profile preservation.
6Browser decoding and available device memory limit the images that can be processed successfully.
7Compression trades some detail for size; do not overwrite your original.
Before you finish

Help and troubleshooting
Frequently asked questions
Is the compressed image lossless?
No lossless guarantee is made. The current WebP and JPG output controls use quality-based encoding, so inspect the result for visible change.
How much smaller will my image become?
There is no reliable fixed percentage. The result depends on image detail, dimensions, source format, previous compression, output format, and quality setting.
Which output is better, WebP or JPG?
WebP is often useful for web delivery and can retain transparency where supported. JPG is broadly compatible for photographs but cannot keep transparency.
How do I keep text from becoming blurry?
Start with a high quality setting, compare at 100%, and avoid shrinking dimensions unless needed. Text-heavy screenshots usually show artifacts sooner than photos.
Does Lalabb upload the image?
The selected image is decoded and encoded in your browser without a Lalabb conversion-server upload for this tool.
Will transparent PNG areas stay transparent?
They can remain transparent in a WebP result when the browser encoder supports it. JPG output replaces transparency with white.
Does compression change the pixel dimensions?
The normal compressor path keeps the original dimensions. The dedicated Image Resizer is the clearer choice when dimensions also need to change.
Should I replace my original with the compressed copy?
Keep the original or a high-quality master. Use the compressed result as a delivery copy after checking text, edges, gradients, and transparency.
Why is the result still large?
The source dimensions and image detail also affect size. Reduce pixel dimensions if the destination does not need them.
Should I replace my print master?
No. Keep the original and use the compressed copy for delivery.
Which output formats are available?
The current compressor exports JPG or WebP, not PNG.
