Most image compression tools send your files to a remote server, process them there, and hand them back. NexCompress does the same work inside your browser tab — faster, private, and with no file size limits imposed by someone else's infrastructure.
Batch processing, format conversion, side-by-side comparison — the things that actually matter when compressing images at volume.
Convert between formats as part of the compression step. PNG files with transparency stay lossless. JPEG and WebP quality is adjustable from 10% to 100% with a slider. The estimated output size updates as you move it — no surprises on download.
Every processed image has a compare view that shows the original and compressed version at full width. It makes the quality trade-off visible before committing to a download, which matters when compressing photos that will be published or printed.
Drop in an entire folder of images at once. NexCompress processes them in sequence and shows a running total of space saved across all files. Download them individually or grab the whole batch as a ZIP with one click.
Web-based compressors typically cap file sizes at 5–10MB and require sign-up for anything larger. NexCompress runs entirely on your device — the only practical limit is your browser's available memory, which handles most workflows comfortably.
Works on Mac, Windows, and Linux in any modern browser.
