How to Use
Drag a folder or multi-select files. PNG, JPEG, WebP, AVIF, GIF, BMP, and TIFF are supported.
Start at 82% for photos and 90% for graphics with text. Use lossless mode only when pixels must stay bit-identical.
Open the before/after preview at 100% zoom on a detail area (text edge, hair, logo stroke) before batch export.
Apply the same setting to the full queue. Processing runs locally — speed depends on your CPU, not upload bandwidth.
Export as ZIP, spot-check 2–3 files, then optionally run winners through WebP conversion for another 25–35% savings.
Start at 80–85% for JPEG product shots. Run one file through the preview at 100% zoom — if label text and fabric weave stay crisp, apply the same setting to the batch. Logos and UI screenshots on PNG often need 90% or lossless mode.
Use our 'Smart Compression' at 80% quality. For web images, this typically yields a 70-90% size reduction while remaining indistinguishable from the original to the human eye.
Lossy compression removes imperceptible color data and high-frequency noise to achieve massive 70–90% file reductions. Lossless compression rearranges image data into smaller binary clusters with 0% pixel loss (ideal for diagrams, typography, and logos).
Resize first, then compress. Downsampling removes unnecessary pixels first, giving you much smaller output files and faster batch processing.
