PasteClean

Tired of Gmail flattening your formatting? Write here first — bold, italics, links, and lists all survive the paste. Now with full dark mode.

PasteClean is a lightweight email composer that solves one frustrating problem: formatting that breaks when you paste into Gmail.

Ever composed a beautifully formatted email only to have it show up as invisible white text on white, mangled headings, or stripped styles?

Gmail aggressively sanitizes pasted HTML — especially content authored in dark mode. PasteClean fixes this before you paste.

How it works:

1. Write your email in PasteClean's rich text editor with bold, italic, lists, links, and headings.
2. Tap "Copy" — PasteClean sanitizes your formatting in the background, stripping unsafe CSS, fixing dark-mode color issues, and converting headings to Gmail-safe bold text.
3. Paste into Gmail. Your formatting arrives intact.

Key features: • Rich text editor with full formatting toolbar (bold, italic, lists, links, headings, and more) • One-tap sanitization that strips dark-mode artifacts, unsafe CSS, and elements Gmail would break • Live preview showing exactly how your email will look in Gmail's light and dark themes • Detailed cleanup report showing every fix applied before you paste • Email size warning if your message approaches Gmail's clipping threshold • Quick handoff to Gmail after copying — open the Gmail app with one tap • Customizable accent colors • Full dark mode support • No account required. No data leaves your device.

PasteClean is built for anyone who cares about how their emails look — professionals sending client-facing messages, marketers previewing campaign drafts, or anyone tired of Gmail mangling their formatting.
