ToolAtlasToolAtlas is a static catalog of small tools that run in the current browser tab. There is no account and no CMS. You pick a job — shrink a scan for Gmail, turn iPhone HEIC into JPG, read a JWT without pasting it into a stranger’s decoder — then open that URL. Favorites and language switching use a stable toolId, not the localized slug.
The homepage is a job picker on purpose. Merge is not compress. HEIC-to-JPG is not the generic format converter. A four-function calculator is not a paycheck page.
What the engines actually do
File tools typically stop around 32 MB. That is a real ceiling, not “unlimited because we are local.”
- Compress PDF redraws pages as JPEG. Scans usually shrink. Selectable text is lost. It is not Ghostscript.
- Video to GIF writes a short GIF89a (about 24 frames, 256 colors, scaled). Not ffmpeg.
- JWT decoder shows header and payload. It does not verify signatures. Treat
alg:noneas a warning. - OCR is English-first (
eng). It is not an ID-card product. - Paycheck calculator subtracts the tax percent you type. It is not the IRS.
- File SHA-256 is SHA-256 only — not antivirus.
Each tool page states its own privacy label. Unless that label says a network query happens, input stays in the tab.
How a page gets published
English and the other public locales (zh-cn, es, pt-br, de, fr, ja, ko) each have their own article. We do not paste English onto a non-English URL. Search, sitemap, and hreflang only include published pages. Pseudo-locales exist for layout testing and stay out of production.
This is a catalog, not Adobe, Smallpdf, or a password manager. If a sibling page owns the job, the article says so and links there.
