Frequently asked questions

How do I compress an image online for free?
Open Compress, drop your file, and use Auto mode for a smaller file or Manual for a specific quality. If the image is already heavily compressed, we return your original so the file size never increases.
Can I convert PNG to JPG or WebP without signing up?
Yes. Use the converter on this page or the dedicated convert tool. Pick JPG, PNG, WEBP, or AVIF, adjust quality, optionally keep EXIF metadata, and download the result.
How do I resize an image for Instagram or LinkedIn?
Use the resizer tool and choose a preset (e.g. 1080×1080 for Instagram posts or 1200×627 for LinkedIn). You can keep aspect ratio or crop to exact dimensions.
Do you store my photos?
Files are uploaded for processing and short-term download only. In production, use cloud storage with a strict TTL and purge policy for your compliance needs.
What can I do with background removal and upscaling?
Background removal gives you transparent PNGs for product photos and composites. Upscaling enlarges images 2× or 4× with high-quality results. Both tools work instantly in your browser.
