Image Compressor - Frequently Asked Questions
Will image compression reduce quality?
Our smart compression algorithm finds the optimal balance between file size and visual quality. For most images, the quality reduction is barely noticeable while achieving significant size reduction (50-80%). You can always preview the result before downloading.
What's the maximum image size I can compress?
You can compress images up to 50MB in size. For best performance, we recommend compressing images under 20MB. The tool handles dimensions up to 10,000×10,000 pixels. Larger images may take longer to process but will still work.
Which format is best for compression?
WebP offers the best compression (25-35% better than JPEG) while maintaining excellent quality. For compatibility, JPEG is best for photos, PNG for graphics with transparency, and GIF for simple animations. WebP is now supported by all modern browsers.
Are my images safe and private?
Yes! All compression happens directly in your browser using JavaScript. Your images are never uploaded to any server - they stay completely on your device. This ensures 100% privacy and security for your sensitive images and documents.
Can I compress multiple images at once?
Currently, our tool processes one image at a time for optimal quality control and to ensure the best compression results. For batch processing, you can compress multiple images sequentially. We're working on batch compression for a future update.
How accurate is the target file size?
Our intelligent compression algorithm iteratively adjusts quality settings to achieve your target file size within 10% tolerance. This ensures you get predictable file sizes while maintaining the best possible visual quality.
Does this work on mobile devices?
Yes! Our Image Compressor is fully responsive and works perfectly on smartphones, tablets, and desktop computers. The interface automatically adjusts to your screen size for optimal mobile experience.
What happens to the original image dimensions?
We preserve the original dimensions by default. For very large images (over 2000px), we may slightly scale down for better performance, but this is clearly shown in the results. You can always check dimensions in the comparison view.
Can I use compressed images for printing?
Yes, but we recommend using high-quality settings (lower compression) for print materials. Target file sizes of 300-500KB with JPEG format typically provide good print quality for standard photos.
