WHY USE IT

Less file weight.
More room to move.

Private by default

Images are decoded and compressed inside your browser. They never leave your device.

Useful formats

Choose WebP for smaller web images, JPG for compatibility, or PNG when transparency matters.

Made for batches

Process several images together, then download each result or save the full batch at once.

A QUICK GUIDE

Choose the right file
for the job.

FormatBest forKeep in mind

WebPWebsites and product imagesSmall files, modern browsers

JPGPhotos and email attachmentsNo transparency

PNGLogos, screenshots, transparencyCan be larger than WebP

For a faster website: try WebP at 75–85% quality, then check the image at its actual display size. A huge original image wastes bandwidth even when it looks sharp.

For social media: use a preset to create the right canvas size first. This avoids blurry crops and keeps important text away from the edges.

For private files: local processing means the original stays on your device. This tool is useful for screenshots, product photos, and documents you do not want to upload.

QUICK ANSWERS

Are my images uploaded?

No. Compression happens locally in your browser. This page does not send your image files to a server.

Which format should I choose?

WebP is a good default for websites. Use JPG for photographs that need broad compatibility, and PNG when you need transparent pixels or lossless output.

Why did a PNG become larger?

PNG is lossless and some already-optimized files cannot be reduced further. Try WebP or JPG when transparency is not needed.
