About image file size
Compression trades file size against image detail. Choose a target in KB and an output format; the tool adjusts encoding quality and, when needed, reduces pixel dimensions to fit. JPG offers broad compatibility. WebP supports transparency. PNG inputs are converted to the selected format, so check fine text and edges before downloading.
Frequently asked questions
Can I compress an image without losing quality?
Re-encoding as JPG or lossy WebP can change image detail. A smaller target may also require fewer pixels. If the original already fits and matches the selected output format, the tool returns it unchanged.
Should I choose JPG or WebP?
Use the format accepted by your destination. JPG is widely supported but needs a solid background. WebP can preserve transparency. Results vary by image, so compare both at the same target when either format is accepted.
Can I adjust quality manually?
This compressor uses a target file size rather than a quality slider. It automatically searches quality settings and reduces dimensions when needed. Raise the target to leave more room for detail.
Will PNG images stay as PNG?
No. The compressor accepts PNG files but exports JPG or WebP. Choose WebP for transparent areas, or select the background color used by JPG.
Does compression keep metadata and animation?
An unchanged original keeps its existing data. Re-encoded results are still images and do not preserve the original camera metadata or color profiles. Check the result if color accuracy matters.
