Move the quality slider – lower values mean smaller files, higher values mean better quality. Check Apply to All to use same setting for every image, or adjust per image using individual sliders below each thumbnail.
Click any thumbnail to activate the compare panel. Drag the center handle left or right to see original vs compressed version. The progress bar and percentage text show exactly how much size you saved.
Click Download All to prepare your files. Choose One by One for individual downloads or Zip to get everything in a single compressed folder.
Start at 70% quality – This preserves most visual detail while cutting file size by 40-60%
Use Apply to All for consistency – When compressing product photos or a gallery, check the box to maintain uniform quality
Double-click any thumbnail – Opens full-screen lightbox to inspect compression artifacts closely
Download Zip for sharing – Saves time when sending multiple compressed images to clients or team members
PNG files convert to JPG – The tool outputs compressed images as JPG for maximum size reduction
Unlike other tools, you see the difference instantly with a draggable slider that reveals original vs compressed.
Use the Apply to All checkbox for consistent compression, or fine-tune each image separately with individual quality sliders.
Your images never leave your device. All compression happens in your browser using canvas elements.
Upload multiple images at once. Each gets its own thumbnail with size reduction badge showing percentage saved.
Works on phones and tablets. The compare slider responds to touch drag, and thumbnails scroll horizontally on small screens.
The live comparison system powers this entire tool. When you select any thumbnail, the right panel displays two images layered on top of each other. The Original label sits on the left, Compressed on the right. Drag the circular handle – the clip path moves with your cursor, revealing one image while hiding the other. Below the visual comparison, a progress bar fills based on your saved percentage. If the file grew (which you may remedy by lowering quality), the text displays the original size, the compressed size, and the precise reduction percentage in green for savings or orange.
Yes, set quality to 85-95% for near-lossless compression while still reducing file size by 20-40%.
JPG, PNG, and WebP files are accepted. All compressed output saves as optimized JPG.
Upload all images, check Apply to All, set one quality value, then download as Zip.
No fixed limit, but very large images may take longer to process since everything runs locally in your browser.
This happens with already optimized PNGs. Lower the quality slider to 50-60% to force smaller output.
Yes, drag the slider handle in the compare panel to see both versions side by side in real time.
