How to use wordok image tools
This page is the long-form UX manual for our browser toolbox. Short version: your files stay on your device while we draw with the Canvas API. Last updated .
Why this exists
Most “free online editors” ask you to upload first and explain privacy later. We invert that: value proposition is fast local edits for screenshots, drafts, and social crops — especially when you do not want a random CDN holding passport scans or family photos.
Tool map
| Job | Where | Notes |
|---|---|---|
| Convert formats | /tools/ → Convert | PNG / JPG / WEBP / BMP / GIF |
| Crop | /tools/ → Crop | Drag handles on canvas |
| Resize | /tools/ → Resize | Lock aspect when needed |
| Watermark | /tools/watermark/ | Dedicated URL + shareable deep link |
| Compress | /tools/ → Compress | Quality slider + size readout |
Watermark — step by step
- Open the watermark page (cleaner than hunting tabs inside the hub).
- Drop an image. You should see a live preview — if not, check that the file is a supported raster type.
- Set text (brand, “draft”, date). Prefer short marks; long sentences collide on mobile widths.
- Tune opacity (≈0.35–0.55 for photos) and slight rotation (−20° to −35°) so marks are harder to crop out casually.
- Use Tile for portfolio protection; use a corner position for subtle credit lines.
- Download PNG. If you need JPG for email limits, convert on the hub afterward.
Privacy model (plain language)
- Image bytes are read into memory in your browser tab.
- Edits are drawn on a
<canvas>; download triggers a local file save. - We do not need an account. Closing the tab discards the in-memory bitmap.
- Analytics (if enabled site-wide) may record page views — not your pixels. See privacy and tools privacy (中文).
Troubleshooting
- Huge photos feel slow: resize first, then watermark. Multi-megapixel phone shots tax low-end phones.
- Transparent PNG looks wrong after JPG convert: JPG has no alpha — expect a flat background.
- GIF animation flattens: Canvas export typically keeps a single frame. Use dedicated GIF tools for animation.
- Corporate locked-down browser: some policies block FileReader / Canvas export — try another browser profile.
FAQ
Is this a full Photoshop replacement?
No. It is a privacy-first utility belt. For layers, masks, and print color management, use a desktop suite — see our image tools scorecard.
Do you store my images for “quality improvement”?
No upload path means we never receive the bytes to store.
