Image Editing Guides

Step-by-step answers to common questions—check here first

PDF watermarking: copyright marks for internal documents

Adding a watermark before sending contracts, quotes or internal docs reduces careless forwarding. This article covers wording that deters misuse, opacity and tiling, and why the file grows after watermarking.

 What are TIFF and AVIF, and when should you convert to JPG

TIFF is the standard for print and scanning; AVIF is a new high-compression format—both often fail to open in browsers and chat apps. This article covers when to use each and how to avoid quality/color drift when converting to JPG.

 How to shrink an oversized GIF: color count, size and frame dropping

GIFs easily hit ten-odd MB—too big to send and slow to load. This article explains the trade-offs of palette colors, dimensions and frame dropping, with a preset that takes 10MB down to 2MB.

Scenarios where it just works

From daily edits to e-commerce, one stop for high-frequency needs

Product & Detail Images

Batch resize, white-bg swap and logo watermark; import a whole folder of Taobao/JD/Pinduoduo shots at once.

DIY ID Photos

Recolor and resize 1-inch/2-inch ID photos—red/blue/white backgrounds, done at home.

Old Photo Repair & Color

AI colorizes B&W old photos and restores blurry ones—make precious memories sharper.

Office Docs & Conversion

PDF compress/split/merge, HEIC/RAW to JPG, image to PDF—nothing left behind, safer.

FAQ

Are the image tools really free?

Yes. All tools are free, no watermark, no sign-up. AI tools include a free daily quota (20/day); upgrade to VIP for more.

Will my images be uploaded to a server?

Compression, resize, watermark and conversion all run locally in your browser—images never touch our server. Only AI cutout, ID photos and restoration upload to our server, deleted right after, results kept 2 hours.

Why does each tool have its own page?

One page does one thing, so settings can be precise and docs clear—and you find the exact tool via search.

About tdd8.cn online image tools

tdd8.cn is a no-sign-up toolbox that splits the most common image jobs into 50 dedicated pages: compression (by quality or to a target KB), resizing, cropping, rotating and flipping, watermarking, format conversion (JPG / PNG / WebP / BMP / ICO), HEIC to JPG, JPG to PDF, ID photo backgrounds, AI cutout, and batch processing of marketplace images for Taobao, JD and Pinduoduo. Every page ships with written instructions, step-by-step guidance and FAQs, so search lands you straight on the right tool.

Compression, scaling, cropping and text watermarks need no model and run entirely in your browser—nothing is uploaded and even a 300-image batch never queues. Only features that require inference (AI cutout, photo restoration, OCR) run server-side, and those files are deleted right after processing. Every tool is free, adds no watermark, and works on a phone.
