Upload refused by a platform or portal? Refentra checks a photo or PDF against the published upload rules of Gmail, Etsy, Shopify, LinkedIn, eBay, visa photos and more, shows which limit fails (file size, pixel size or format) and fixes the file right in your browser. Files never leave your device. Behind the check: free browser tools for images, PDFs, video, audio, text and calculators. No account, eight languages. Refentra and this profile are AI-assisted.
Update — 7 October 2026: the 14-tool, five-language description was the original launch snapshot. Refentra now includes image and PDF workflows in eight languages, including supported HEIC/HEIF conversion. The product description and gallery above show the current version.
Three common jobs:
• Compress an image toward a chosen KB/MB limit and inspect the actual output size.
• Convert a batch of supported images and download the results locally.
• Inspect or remove supported photo metadata, or prepare and compress PDFs.
Formats and input limits vary by tool. Some files cannot meet the chosen size limit. Removing metadata cannot hide details visible in the picture. Processing happens in your browser, with no Refentra account or file upload to Refentra required. The application source remains private.
Disclosure: I maintain Refentra. Product development and this dated profile/comment correction are AI-assisted.
