How do I reduce image file size online free under 100kb with this tool?

Enable Smart Goals and choose WebP or JPG at 65-75% quality to reduce image file size online free under 100kb. Combine it with Smart Resize and EXIF removal to satisfy email, blog, and app store limits.

What's the difference between lossy and lossless compression?

Lossy compression (our default) removes some data to achieve significant file size reduction. It's 'smart' because it removes information humans typically can't see. Most images compress 50-80% smaller with no visible quality loss. Lossless compression keeps all original data but only achieves 10-30% size reduction. We offer both modes - choose lossless if you need pixel-perfect preservation for archival purposes.

How much can I compress an image without losing quality?

It depends on the image type: JPG photos - 70-90% quality setting typically achieves 50-70% size reduction with no visible quality loss. PNG graphics - Can be reduced by 40-60% using color palette optimization. GIF animations - Usually compress 30-50% by removing duplicate frames. Web images - 80% quality setting is the sweet spot for most use cases.

Can I compress multiple images at once?

Yes! Batch processing supports up to 50 images simultaneously. Simply select all files you want to compress, apply your preferred settings, and click 'Compress All'. You can download results individually or as a single ZIP archive.

Will compression reduce image resolution or dimensions?

No, compression only reduces file size by optimizing data, not by changing pixel dimensions. A 4000×3000 image will remain 4000×3000 after compression. If you want to change dimensions, use our Image Resizer tool instead (or enable 'Smart Resize' option during compression).

Is it safe to upload my images? What about privacy?

Absolutely safe! All image processing happens locally in your browser using client-side JavaScript. Your images never leave your device or get uploaded to our servers. Files are automatically cleared from browser memory after you close the tab. We cannot access, view, or store your images.

What file formats are supported?

We support the most common image formats: JPG/JPEG (best for photos and complex images), PNG (best for graphics, logos, and images requiring transparency), GIF (both static and animated GIFs supported), WebP (modern format with excellent compression), and AVIF (next-gen format for maximum efficiency).

Why do some images compress better than others?

Compression effectiveness depends on image content: High compression potential - Photos with uniform backgrounds, simple graphics, illustrations. Lower compression potential - Detailed textures, grain, noise, complex patterns. JPG already compressed - Re-compressing a previously compressed JPG yields minimal additional reduction. PNG screenshots - Often compress very well (60-80%) if they contain large solid color areas.

Can I compress images for specific use cases (web, print, social media)?

Yes! We offer preset modes: Web Optimized (80% quality, strips metadata, perfect for websites), Social Media (platform-specific settings for Instagram, Facebook, Twitter), Email Friendly (targets <500KB per image for email compatibility), Print Quality (95%+ quality, maintains color accuracy for printing), and Custom (manually adjust all settings for specific needs).

What's the maximum file size I can compress?

Each image can be up to 50MB. For batch processing, the total combined size can be up to 500MB. If you have larger files, you can compress them individually or use our desktop app for unlimited processing.

Will compression affect image colors or sharpness?

At recommended quality settings (70-90%), there's no perceptible change to colors or sharpness for screen viewing. If you're preparing images for professional printing, use the 'High Quality' or 'Print' preset (95-100% quality) to maintain perfect color accuracy and detail.

Can I undo compression or restore the original quality?

No, compression is irreversible. Always keep a backup of your original files before compressing. However, since compression happens locally in your browser, your original files remain untouched on your device - only the downloaded compressed versions are modified.

How does this compare to Photoshop's 'Save for Web'?

Our online compressor produces similar results to Photoshop's export features, but with several advantages: Free (no expensive software license required), Easier (no learning curve or complex settings), Faster (batch process 50 images vs. one at a time), Accessible (works on any device with a browser), Smart defaults (automatically optimized settings for each image). However, Photoshop offers more granular control for professional workflows requiring pixel-perfect adjustments.

Why are my compressed images still large?

Possible reasons: Already compressed - Image was previously compressed, leaving little room for further reduction. High detail/noise - Photos with grain, textures, or detailed patterns don't compress as well. Wrong format - PNG used for photos (use JPG) or JPG used for graphics (use PNG). Settings too conservative - Try lowering quality setting from 90% to 80%. Try adjusting compression level or converting to a more appropriate format.

Can I use compressed images for commercial purposes?

Yes! Compressed images retain all rights and ownership. Our tool only processes your images - we don't claim any rights to your content. Use compressed images freely for personal, commercial, or business purposes without attribution or licensing restrictions.
