Compress images privately in your browser

Image Compressor reduces file size directly in your browser. You can compress JPG images, optimize PNG files, convert suitable assets to WebP, and resize files before export without sending them to a server.

It is built for practical everyday tasks such as preparing website assets, shrinking screenshots for email, or making product images lighter before upload.

Privacy note: All image processing happens locally in your browser. No file data is uploaded, stored, or inspected remotely.

1. Upload one or more JPG, PNG, or WebP files.
2. Choose a preset such as Balanced or Smallest file.
3. Open advanced settings if you want a specific output format or resize limit.
4. Click Compress images.
5. Review the results and download individual files or everything at once.

• Reduce image size before website or CMS upload.
• Prepare lighter attachments for email, chat, or support tickets.
• Convert oversized PNG or JPG assets into more web-friendly formats.
• Resize large photos before sharing them with clients or teammates.

JPEG and WebP files usually show the clearest size reduction. PNG behaves differently because lossless optimization is more conservative than aggressive lossy compression.

• Use JPEG or WebP when smaller output size matters most.
• Keep PNG when transparency is important.
• Resize dimensions before export if you need a larger file size drop.
• Expect photo-style images to compress more than flat graphics or icons.

• JPEG does not preserve transparency, so transparent areas are flattened.
• PNG optimization may help, but the result is often less dramatic than JPEG or WebP compression.
• Using the same settings for a batch keeps the workflow simple, but results still vary per file.
• Very large images can take longer because everything runs locally in your browser.
