How does the FileVert image compressor work?

The FileVert image compressor allows you to compress JPEG, PNG, WebP and AVIF images directly in your browser. Unlike online image compressor tools, no files are sent to a server: everything is processed locally, individually or in bulk. Reduce image weight becomes simple with this free photo compression, no signup required.

What "in your browser" means

  • No files are sent to a server
  • No remote storage
  • No external access to your data
  • Works even offline

Two modes to compress images

Compress image by image or compress images in bulk according to your needs.

Classic mode — Compress image by image

Ideal for compressing JPEG or compressing PNG individually with precise quality control. Reduce image weight becomes simple and fast.

Folder mode — Compress images in bulk

Compress complete image folders in a single operation. You get exactly the same structure, with all subfolders, all compressed images.

Individual compression

Compress one image at a time with full control over each file

Mass compression

Process multiple images simultaneously to save time

Automatic batch resize

Smart resizing automatically applied to an entire folder

Resize images directly in your browser

The FileVert image compressor also allows you to resize your images (JPEG, PNG, WebP, AVIF) before or during compression. You can reduce dimensions (width, height, resolution) image by image or in bulk, without sending to a server, directly in your browser.

Automatic intelligent resizing

The system automatically analyzes your images and suggests the optimal size for each folder or group of images. No need to resize each photo manually: FileVert detects the average width of your images and suggests a consistent size adapted for the web.
