When you set a target of 30KB, the tool uses a binary search algorithm to find the optimal compression quality. It starts at 50% quality and repeatedly halves or doubles the search range — converging on the highest quality that keeps the file under 30KB. For PNG files (which are lossless), it scales image dimensions instead. This typically converges in under 20 iterations, taking less than a second.
For photographs, JPG or WebP format gives the best quality at 30KB. PNG files are significantly larger at the same visual quality — if your image doesn't need transparency, convert to JPG or WebP using the format selector in settings. For images with text or sharp graphics, stay with PNG even if the file is slightly larger, as JPG compression creates visible artifacts around edges.
Very large images (e.g. 10MB+ RAW photos) or highly detailed PNGs may not reach 30KB without significant quality loss. In such cases, the tool compresses to the minimum quality (or minimum dimensions for PNG) it can. You'll see the actual output size in the before/after view. If the result is still over 30KB, consider cropping or resizing the image before compressing.
Common questions about compressing images to 30KB.
Upload your image and click "Compress to 30KB". The tool automatically adjusts compression quality to get as close as possible to the 30KB target while maintaining the best possible image quality.
Yes. PNG images are compressed by resizing dimensions when needed because PNG uses lossless compression. JPG and WebP images use quality adjustment for more accurate file size control.
Most images retain good visual quality after compression. Extremely large images compressed to very small sizes may show some quality loss depending on the original file.
Yes. All compression happens directly in your browser. Your files are never uploaded to our servers, ensuring complete privacy and security.
If your image is already below 30KB, it will remain unchanged and no unnecessary compression will be applied.
Yes. Upload multiple images and compress them together. Each image is processed individually and can be downloaded separately or as a ZIP archive.
The tool supports JPG, JPEG, PNG and WebP image formats. More formats may be added in future updates.
Some compression is always required to reduce file size, but our algorithm preserves as much visual quality as possible while reaching the target size.
Yes. This tool is suitable for compressing photos for government forms, competitive exams, passport applications and other portals that require image size limits.
Yes. You can compress passport photos to meet required file size limits without manually adjusting quality settings.
Yes. Many government recruitment and examination portals require images below specific size limits such as 20KB or 50KB. This tool helps you achieve those targets.
Yes. The compressor works on Android phones, iPhones, tablets, laptops and desktop computers using any modern web browser.
Yes. It works on Windows, macOS, Linux and ChromeOS without installing any software.
No. Everything works directly inside your browser. No software installation or plugins are required.
Yes. Compressing images to 30KB helps reduce email attachment size and makes sharing much faster.
Yes. Smaller images improve website loading speed, Core Web Vitals and overall user experience.
For JPG and WebP images, dimensions usually remain the same. PNG images may be resized if necessary to reach the requested file size.
Large images are supported, but extremely large files may take longer to process depending on your device and browser performance.
Yes. Since processing happens locally in your browser, the tool can continue working after the page loads even if your internet connection is interrupted.
