Reduce file size
Optimize website images, article covers and everyday sharing. Suitable dimensions and formats can reduce image transfer size; results depend on the source and your settings.

Free Online Image Compressor
Reduce image file size, resize and convert formats in the IDEAL NEO Image Studio. Compare the original and result with the slider to find the right balance between quality and size.
Lighter images. Easier sharing.
Adjust and compare
Drag the divider and zoom in to inspect details before adjusting format, quality or dimensions. Choose a smaller file without blindly sacrificing clarity.
Process on your device
Your browser reads and processes the image you select. The tool does not upload your image file to a server. Download the result when you are ready.
How to compress an image online
Choose an image
Drop, select or paste an image. Process one image at a time, up to 20 MB and 20 megapixels.
Adjust and inspect
Choose WebP, JPEG or PNG. Adjust quality and dimensions as needed, then compare file sizes and image detail.
Download and continue
Save the result with Download image. Use Replace image to process another file, or Clear image to return to the starting view.
WebP, JPEG or PNG: which should you choose?
WebP · Web images and transparency
Supports transparency and works well for web images. Adjust quality and use the comparison preview to inspect edges and details.
JPEG · Photos and everyday sharing
Useful for photos and other continuous-tone images, with adjustable quality. JPEG does not support transparency; this tool fills transparent areas with white.
PNG · Transparency and crisp edges
Preserves transparency and uses lossless browser encoding, so the quality slider does not apply. Re-encoding may increase size, and resizing changes the source pixels.
Image compression FAQ
Is this image compressor free?
It is currently free, requires no account and has no configured daily processing limit. Each image is still limited to 20 MB and 20 megapixels, and performance depends on your device.
Which input and output formats are supported?
You can select JPEG/JPG, PNG, WebP, AVIF and BMP images, subject to browser decoding support. Output options are WebP, JPEG and PNG. AVIF and JPEG XL output are not currently available.
Where is my image uploaded?
Your image file is not uploaded. Compression and conversion run in your browser on your device. Loading the page or example images still uses network requests. On-device processing refers to image files, not an absence of all website network services.
Will quality change? Can you guarantee an 85% reduction?
JPEG and WebP quality settings may change detail. Savings depend on prior optimization, image content, output format and dimensions. There is no fixed reduction rate or promise of lossless results. Compare before downloading.
Why is the output larger than the original?
The source may already be optimized, or the chosen format may not suit it. PNG re-encoding can increase file size. Try WebP or JPEG, lower quality or smaller dimensions. The tool displays the actual size change.
Can I reduce file size without resizing?
Yes. Leave Resize off and choose a suitable format and quality. Original dimensions are retained, but a smaller file or pixel-identical output is not guaranteed.
Can I batch-compress images or process GIF and HEIC?
The tool currently processes one image at a time, with no batch jobs or GIF/HEIC input. Animation is not retained. Convert such files to a supported still-image format first.
Why compress website images?
Images can account for a large share of page transfer size. Appropriate compression reduces download data and can help loading performance. Actual speed also depends on hosting, caching, scripts and network conditions.
How do I clear the result or choose another image?
After downloading, choose Replace image for another file, or Clear image to remove the current preview and download link. Clearing does not delete the original or any downloaded files on your device.
Can I use it on a phone?
Use a modern mobile browser with the required image decoding and Canvas encoding support. Large images consume memory and processing speed varies by device. If a format fails, try another format or a smaller image.
