Question 1

How do I compress an image without losing quality?

Accepted Answer

Upload your image and use the quality slider to adjust compression level. A quality setting of 80-90% typically produces files 50-70% smaller with virtually no visible quality loss. The tool shows you the original and compressed file sizes in real-time, so you can find the sweet spot. For photos, JPEG compression at 85% quality is usually indistinguishable from the original.

Question 2

What compression formats are supported?

Accepted Answer

Our tool supports compression to JPEG, PNG, and WebP formats. JPEG is best for photographs and complex images. PNG is ideal for images with transparency or sharp edges (like logos). WebP offers superior compression — typically 25-35% smaller than JPEG at equivalent quality — and is supported by all modern browsers.

Question 3

How much can I reduce my image file size?

Accepted Answer

Typical compression results vary by image type: JPEG photos can often be reduced by 50-80% with minimal quality loss. PNG files can be reduced by 10-50% depending on content complexity. Converting PNG to WebP can reduce size by up to 80%. Converting PNG to JPEG (for non-transparent images) can reduce size by 70-90%.

Question 4

When should I compress my images?

Accepted Answer

Compress images whenever file size matters: uploading to websites (faster load times), sending via email (attachment size limits), posting on social media (platform size limits), storing photos (save disk space), and meeting web performance targets. Google recommends keeping images under 100KB for optimal page load speed.

Question 5

Is there a file size or dimension limit?

Accepted Answer

Since all processing happens in your browser, the main limitation is your device's memory. Most modern devices can handle images up to 20-30 megapixels comfortably. There's no arbitrary file size limit imposed by our tool. However, very large images (50+ megapixels) may be slow to process on older devices.
