As a working interior designer, I kept switching between sites just to resize photos, compress PDFs, convert units. All free tools — but the switching killed my flow. Toolbox for Designers puts them in one place. Tools designers actually use, curated by a designer, in one tab left open all day. Includes: photo resize, compress, rename, watermark, HEIC converter, PDF merge, compress, convert, page numbers, unit, color & currency converter. Free. Built by C/O Design Consulting, Shenzhen.
