Compress JPEG Images to a 300KB Target
When a form or CMS asks for a JPEG near 300KB, choose the 300KB target before uploading. Lynote compresses toward that file size and shows the result afterward. This is easier than adjusting quality percentages repeatedly.
Compare JPEG Images Before and After Compression
A 300KB JPEG may need to preserve text, faces, or product detail. Compare the original and compressed image side by side with file size and dimensions. Use the preview to decide whether the result is ready for download.
Batch Compress JPEG Images to 300KB
If you have many JPEGs for listings, applications, or records, process them together. Upload multiple files up to 50MB each and apply the 300KB target across the batch. The workflow keeps a whole set of images consistent without file-by-file repetition.
