PNG files are lossless and faithful, but they can be several times the size of an equivalent JPG — a real liability when uploading product shots, blog images, or email attachments. Enhydra RPO converts up to 200 PNGs to JPG in a single run and hands you one ZIP to download.
One thing to settle before you start: JPG has no transparency channel. Any see-through pixels in your PNGs will be filled with a solid color. The converter offers white or black — pick whichever matches where the image will land.
JPG cannot store an alpha channel. When a PNG with transparent or semi-transparent areas is encoded as JPG, those pixels are composited against a solid fill before the file is written. Enhydra RPO gives you two fill options: white for images that will sit on a light background, and black for dark-themed UIs or presentations.
This compositing is permanent in the JPG output — there is no way to recover the original transparency from the result. If your workflow requires alpha at the destination, WebP or PNG are the correct output formats.
The converter applies a high-quality default so every output is a clean baseline. If you need to hit a specific file size or fine-tune visual quality, stack the Compress tool in the same run — it lets you enter a quality value from 1 to 100 or a target size in kilobytes. Because both operations run in a single decode-encode pass, there is no double-encoding penalty on the output quality.
Stacking Compress alongside PNG→JPG is the standard workflow when preparing images for a size-limited upload portal or a web page with a performance budget.
By default the converter strips all EXIF data — GPS coordinates, camera model, shooting parameters — from the output JPG. This is the privacy-safe choice for images that will be published online.
If you need metadata preserved (for archival, stock photo licensing, or print prepress), tick the Keep metadata (EXIF) checkbox before starting the job. Files are auto-deleted roughly 30 minutes after your ZIP is ready; no account or tracking is involved.
JPG is lossy, so some data is discarded. The converter uses a high-quality default, and the visible difference on photographs is usually negligible. Hard-edged graphics and text fare worse under JPG compression, so PNG may be a better final format for those.
Transparent pixels are filled with the background color you choose before converting — white or black. There is no way to keep transparency in a JPG file, so pick the color that matches where the image will be used.
Yes. Add the Compress tool on the same page alongside the format converter. Both run in one pass per photo — no extra quality loss from double encoding.
Up to 200 files per run, with a maximum of 80 MB per individual file. Results are packaged as a single ZIP for download.
