Compress Images to a 100KB Target Size
If a form asks for an image under 100KB, guessing with quality sliders can be frustrating. Choose the 100KB target before uploading your JPEG, PNG, or WebP file. The tool compresses toward that limit and lets you review the result before download.
Compare Images Before and After Compression
A 100KB file often needs to stay clear enough for IDs, profile photos, or small product images. Check the compressed preview beside the original and review the file size and dimensions. This helps you decide whether the 100KB version is ready for submission.
Batch Compress Images to 100KB
When a portal needs multiple 100KB attachments, batch compression saves time. Upload several supported image files, each up to 50MB, and apply the same 100KB target. You can prepare a full set of photos without repeating the workflow file by file.
