Blinkimg is a free image compressor and converter for JPG, PNG, WebP, AVIF and HEIC. Drop up to 50 photos, type a size in KB, and get files that fit. We built it for the moment an upload form says "file too large". Passport and visa portals, job applications, exam forms, email attachments: each has a limit, and most tools only guess at it. Blinkimg treats the number you type as a hard cap. It lowers the quality first, then the pixel size, and it never hands back a file over the limit. What you can do on blinkimg.com: • Compress JPG, PNG, WebP and AVIF in batches of 50, no signup • Convert between formats, including iPhone HEIC to JPG • Resize, crop, rotate and add text in the browser editor • Turn photos into one PDF under a size limit • Remove EXIF and GPS data before you share a photo • See how much image weight any web page could save For developers, the same engine runs behind a REST API and an MCP server for AI agents. Every account gets 500 free API credits a month. Uploaded files are deleted within 24 hours, and location data is stripped from every download by default. Here we post about image sizes, formats and upload limits, with numbers we measured on real files.
