Frequently Asked Questions
Why is WEBP compression highly recommended?
WEBP is a modern image format developed by Google that offers superior lossless and lossy compression. It can make image files up to 30% smaller than traditional JPEG and PNG files while preserving similar visual clarity.
Is there a size limit for images I can upload?
Since we do not upload files to a server, we do not enforce any strict limits. However, to keep browser tab memory stable, we recommend images under 20MB. Standard phone photographs and screenshots compress perfectly.
Does 'Lock Aspect Ratio' matter when resizing?
Yes, locking the aspect ratio ensures that when you adjust the width, the height scales proportionally, preventing the image from appearing stretched or distorted.
