Compress, resize and
convert images in bulk
Compress, resize, crop and convert your images in bulk, without losing quality. Supports JPG, PNG, WEBP, AVIF, GIF, SVG and PDF.
One tool, four operations
Fine-tuned compression, resizing, cropping and conversion — on as many files as you need.
Built for batches, not single files
Most online image tools are designed around one file at a time, then meter you once you need more. This one starts from the opposite assumption: drop in a folder's worth of photos, apply the same treatment to all of them, and download the result as a single ZIP archive. There is no per-batch quota, no account and no paid tier gating the file count, because the work happens on your own machine rather than on a server someone has to pay for.
The practical limit is your device's memory. A few hundred photographs on a normal laptop is routine; the constraint you will hit is patience on very large batches, not a plan.
Nothing is uploaded — and you can verify it
Every operation runs client-side. The codecs that read HEIC, encode AVIF and optimise PNG are compiled to WebAssembly and execute inside your browser, so your files are never transmitted, queued or stored anywhere. If you want proof rather than a promise: load this page, disconnect from the network, and the tool keeps working normally.
That has a side effect worth knowing. Because each image is re-encoded locally, exported files do not carry the original EXIF block — camera model, capture timestamp and GPS coordinates are dropped. For client photographs or anything falling under GDPR, processing that never transmits the file is a different proposition from a service that uploads it and promises deletion afterwards.
