Practical guidance
Image compression is the simplest way to make a page, email, shop listing, or document feel faster without redesigning the image itself. This compressor lets you choose a quality level and output format, then compare the original and result so the final file is smaller but still useful.

Privacy and local processing
For this tool, ordinary image processing happens in the browser using front-end APIs. The file is loaded into the current page, processed in memory, and made available as a download. Your generated result is not permanent unless you download it, and refreshing the page clears the working state.
Additional FAQ
Should I always choose the lowest quality?
No. Very low quality can create visible artifacts. A practical starting range is often 70 to 85 for photos, then adjust after previewing.
Is PNG compression the same as JPG compression?
No. PNG is usually better for sharp graphics and transparency, while JPG and WebP often create smaller files for photos.
Can I compress many files together?
Yes. Upload a batch, apply shared settings, and download the finished results together when batch export is available.
FAQ
How can I compress an image for email or a website?
Upload the image, choose a lower quality value, then process it. A lower quality setting usually reduces file size, especially for JPG and WebP output.
Can this tool compress JPG files?
Yes. You can compress JPG files and export them as JPG, WebP, PNG, or keep the original format when supported.
Can this tool compress PNG files?
Yes. PNG images can be processed locally. For photos, WebP or JPG output may create a smaller file than PNG.
Will compression reduce image quality?
Usually yes. Compression trades some visual detail for a smaller file. Use the preview and metrics to choose a quality level that still looks acceptable.
Can I compress multiple images at once?
Yes. Upload multiple images, process the batch, and download all compressed images as a ZIP file.
Are my images uploaded?
No. Standard image compression happens locally in your browser and images are not uploaded to a server.
