Compress PNG Ruby Overview
Compress PNG images to smaller sizes while preserving visual quality and full alpha transparency. Choose a compression level, set a percentage reduction, or target a specific output file size to meet web, email, and storage limits. Smart palette optimization reduces file sizes by up to 80% without noticeable artifacts, making it ideal for optimizing UI assets, screenshots, logos, and graphics for faster page loads and lower bandwidth. Upload a .png and get an optimized .png suitable for fast delivery and efficient archiving. Includes a ready-to-use Ruby SDK.

File
File Supported formats: .pngFile to be converted. Value can be URL or file content.
CompressionLevel
Collection Default: ExtremeImage compression level.
Values: Lossless Good ExtremeCompressionPercentage
IntegerCompress the image to a target size, given as a percentage of the original file size. A lower value produces a smaller file, so 20 aims for roughly 20% of the original size and 90 applies only light compression. Overrides CompressionLevel unless it is set to lossless.
CompressionFileSize
IntegerCompress the image to a target file size in kilobytes. A lower value produces a smaller file. This is a best-effort target: the result is the closest size at or below the requested value that the format allows. Overrides CompressionLevel unless it is set to lossless.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
