Free Online Image Compressor - Reduce JPG, PNG & WebP Sizes
How Much Can You Actually Shrink a Photo?
A standard iPhone photo runs 3–8 MB. Most websites, email tools, and messaging apps prefer images under 500 KB. Our free image compressor bridges that gap — reducing file sizes by up to 90% while keeping your photos looking sharp. Whether you're preparing images for a website, portfolio, or social media, you get smaller files without the telltale blur of over-compression.
Quality vs. Size: Finding the Sweet Spot
The quality slider is the most important part of this tool. Dragging it to 80% gives you a file that's 60–70% smaller with no visible difference on screen. Drop to 60% for maximum reduction — most users can't spot the difference at normal viewing size. The compression runs entirely in your browser via WebAssembly, so no files are uploaded anywhere.
JPG, PNG, and WebP — All Supported
JPG files compress by reducing color information. PNG files compress losslessly by default, but switching them to WebP can cut size by 30% more. If you're building a website, WebP is the modern standard — faster load times, better Google PageSpeed scores. Our compressor handles all three formats and lets you pick your output type.
Who Uses an Image Compressor?

Your Files Stay on Your Device
Most free online compressors upload your photos to a server, compress them, then send them back. That means your images pass through someone else's system. ImageXpo runs entirely in your browser — compression happens on your hardware. Nothing leaves your device. No account needed, no file size caps.
Frequently Asked Questions
How do I compress an image without losing quality?
Set the quality slider to 75–85%. At that range, the file becomes 60–75% smaller but the difference is invisible at normal screen viewing size. Our compressor removes data the human eye can't detect — it doesn't blur or smear your image.
Can I control how much it compresses?
Yes. The quality slider gives you full control. Higher = bigger file, sharper look. Lower = smaller file, slight quality trade-off. The live preview shows you the result before you download.
Is there a file size limit?
No. Because compression runs on your own device via WebAssembly, we have no server costs to protect. You can compress a 50-megapixel photo or a batch of 20 images — there's no upload quota.
Is my photo safe here?
Yes. Your photo never leaves your browser. The compression runs locally on your hardware using WebAssembly. We have zero access to your files — they're processed entirely in your browser's memory and cleared when you close the tab.
