Hi Product Hunt — I'm sharing PicNexo, a small set of browser-based image tools for preparing attachments, changing file formats and making website images smaller.
You can select up to 20 JPG, PNG or still WebP files, review them before processing, compare the output sizes, then download individual results or a ZIP. No tool account is needed.
Image processing happens on your device. PNG compression uses Oxipng in a worker; JPG and WebP use the browser's encoder. They have different tradeoffs: PNG optimization is lossless, while JPG/WebP quality settings can change visible detail. JPG output fills transparent areas with white. Settings changes reprocess the original batch, and a cleared run cannot overwrite a newer batch's results.
The current version handles still images only. It does not resize images, support HEIC, or guarantee an output such as 100 KB. A format conversion can also make a file larger, so the result size is shown rather than assuming every conversion is a saving.
The website has optional Google Analytics for visits and aggregate tool use. You can reject it and still use the tools; images and filenames are not included in PicNexo analytics events.
I'd appreciate feedback on the batch workflow and on whether the format and transparency tradeoffs are clear. If something fails, the tool, browser and error message are useful details; there is no need to share your private image.
