Compress Image for eBay — Free Online

For a used item, pay particular attention to the condition details that distinguish it from a new one. Compression can soften a scratch, a worn seam or lettering on a label. Do not choose an output merely because it is smaller if it obscures information a buyer needs. A close-up may deserve a more generous budget than a simple overview against a plain background.

Refer to eBay’s picture guidance for the current listing workflow. This tool does not evaluate whether an image accurately represents an item or satisfies a marketplace policy. It also does not add a white background, remove watermarks already in the source or determine which photograph should be the first listing image.

The preset avoids enlarging a small source, and automatic target search may reduce a large one further. Verify the final width and height alongside the bytes, rather than assuming the 1600-pixel starting value will always remain. Keep separately named copies for the overview and condition close-ups. Compress Image for Amazon offers another marketplace workflow; do not overwrite the original to reuse a single compressed file everywhere.

Open one JPG, JPEG, PNG or WebP and review the preset before starting. A target is a maximum file budget, not an exact output weight. These pages use decimal units: 1 KB is 1,000 bytes and 1 MB is 1,000,000 bytes. You can change the target, select the output format and switch optional resizing on or off. Where a maximum long edge is preset, both dimensions scale together and smaller sources are not enlarged. Use Resize Image first when an exact canvas or crop is required.

The compressor tries encoding settings and measures their output. JPEG and WebP can discard detail; PNG compression may reduce the color palette. A demanding byte budget can also trigger proportional downscaling, even after you choose starting dimensions. The result shows the final dimensions and whether the maximum was met. An unsuccessful attempt remains clearly marked; choosing a bigger budget or changing dimensions may be necessary. JPEG puts transparency on white. For HEIC or AVIF, use Image to JPG before opening the result here.

Compare fine text, edges and important details before downloading. A smaller number is useful only if the image remains suitable for its destination. Return to the original when trying another setting, rather than repeatedly compressing the last copy. An already-fitting source is returned unchanged, including metadata, only when its format and dimensions also need no change. Processing is free and local to your browser, without signup or image uploads to our processing servers. The tool handles one file at a time and does not replace files in your library, upload to another account or submit a form for you.
