Choose your output format and target size for full control over image conversion and compression.
This tool is built for situations where you need more control than a simple size-only compressor — for example, converting a PNG screenshot to a smaller JPG file, or keeping transparency by targeting PNG output at a specific size. You can pick JPG, PNG, or WEBP as your output format and set any target size in kilobytes.
JPG output generally achieves the smallest file sizes because of lossy compression, while PNG preserves transparency but compresses mainly through resolution scaling since PNG has no quality slider. WEBP offers a modern middle ground with strong compression and optional transparency support.
Yes — upload a PNG and select JPG as the output format. Note that transparency will be replaced with a white background.
WEBP is supported by all modern browsers and most platforms, but for maximum compatibility with older software, JPG remains the safest choice.
