KLOORAQuestions and Answers
Quick, direct answers to common questions about our free tools and the tasks they solve. Each answer links to the tool that does the job.
Images and photos
How do I reduce an image to 100 KB?
Open the Image Compressor, add your picture, type 100 in the target size box and press Compress. The tool lowers quality until the file is under 100 KB, then you download it. Nothing is uploaded.
How do I compress a photo to 50 KB or 20 KB?
Type 50 or 20 in the target size box of the Image Compressor. Very small targets work best if you also set a smaller maximum width, such as 500 pixels.
How do I make a photo smaller without losing quality?
Reduce the pixel dimensions first, then compress. A photo at 1000 pixels wide looks sharp on most screens and is far smaller than a full camera photo.
What is the difference between JPG, PNG and WebP?
JPG is small and good for photos. PNG is lossless and supports transparency, so it suits logos and screenshots. WebP is usually smaller than both and is best for websites.
How do I convert PNG to JPG?
Open the Image Converter, add the PNG, choose JPG and download. Transparent areas become a solid colour because JPG has no transparency.
How do I resize an image to an exact size?
Use the Image Converter and Resizer. Enter the width or height in pixels, or a percentage, then download the resized file.
Are my photos uploaded when I compress them?
No. The compression runs inside your browser, so the photo never leaves your device.
