Before you upload
Image compressor.
Check every small word.
Make a JPEG or WebP delivery copy of one static product ad. Choose a target file size, compare the actual bytes and previews, and download the copy you reviewed. Pixel dimensions stay the same.
PNG, JPEG or WebP · up to 15 MiB, 16 MP and 4096 px per side. Animated PNG/WebP are not supported. The image stays in this page and is not uploaded.
WebP can retain transparency. Verify that your destination accepts WebP. Both outputs use lossy encoding; neither preserves every pixel or label automatically.
1 KB = 1,000 bytes. This is your budget, not a platform specification. If the tried settings cannot meet it, the result says so.
The tool tries lower quality settings down to 15 if needed, keeping pixel dimensions. The number is an encoder setting, not a visual-quality score.
Fewer bytes.
A deliberate comparison.
Choose an image to compare a delivery copy with the original. Nothing is generated.
A file-size result, then your judgement
A smaller file still has a job.
Read the opening, product label and final action in the downloaded file. The tool checks bytes, not legibility. A quality parameter is not a visual score. There is no guarantee of a smaller file, lossless output, identical colors or readable generated lettering.
PNG is accepted as input; output is JPEG or WebP, not an optimized PNG. JPEG flattens transparent areas onto cream. If your destination needs another format, use an encoder that supplies it. Check the actual publishing service's requirements and its final uploaded preview.
