: How to use it, features, and the business problems it solves

What is RemoveHandwriting?

RemoveHandwriting is an AI tool that removes only the handwriting from images, PDFs, and scanned documents. It erases answers, notes, red-pen marking, and underlines written on worksheets and test papers, while keeping the printed questions, tables, diagrams, and page layout as they are. It is designed for cases such as returning a filled-in worksheet to a blank state so it can be used again.

The service is operated by Shenzhen Liwa Software Technology Co., Ltd. in Shenzhen, China. Besides the web version that runs in the browser, there are official apps for iPhone, iPad, and Android, and credits on the same account can be used everywhere. The website and the apps are available in Japanese. Pricing is credit-based, and new users receive 3 free credits when they sign up.

How to Use

1. Open the website or the app

   On the official website, choose under "Remove Handwriting" whether to process a single image, a batch of images, or a PDF. On a smartphone, the official app from the App Store or Google Play lets you take a photo with the camera and process it right away. You sign in with an email verification code or a Google account.

2. Upload a file

   Images can be JPG, PNG, JPEG, WEBP, HEIC, or HEIF, up to 10MB per file. PDFs can be up to 50MB and 50 pages, and you choose which pages to process (up to 20 pages per run when signed in; the guest trial is limited to 1 page).

3. Choose a model and process

   For everyday black-and-white documents, choose Standard (1 credit per image, a few seconds). To keep paper color or color printing, choose Color (3 credits). For pages with dense writing or difficult scans, choose Ultra (5 credits, about 1 minute per image).

4. Check the result and erase leftover strokes by hand

   If the automatic result leaves a few strokes behind, you can remove just those with the manual eraser. According to the official guide, the manual eraser uses no extra credits.

5. Download

   Download the cleaned image. For PDFs, the processed pages can be exported back into a PDF. If even Ultra cannot clean a page, you can send it to manual correction by expert staff (8 credits per image, usually within 24 hours).

This is the image processing screen of the web version. You drop an image or PDF into the central box and switch between Standard, Color, and Ultra under "Model". The buttons below lead to batch processing, PDF processing, and manual correction by expert staff. You can also try it with sample images.

Features

Turn a filled-in worksheet back into a blank one

The main use is to remove what has been written on study worksheets, workbooks, and test papers to make a blank copy for practicing again. On the official site's "Who it is for" list, students and teachers come first. When you cannot get another copy of a handout or no longer have the original, you can produce something close to the unwritten state from a single photo.

The demos on the official website include a Japanese English-class worksheet. From a photo taken on a desk, the handwritten English answers and red-pen corrections are removed, and the background outside the paper is cropped away.

Beyond study materials, the official site says it can also be used for documents such as contracts and forms, marked-up drafts, and organizing scanned records. However, the site itself notes that writing dense enough to overlap printed text, or blurry or heavily shadowed photos, can leave strokes behind or damage printed characters. In that case, move on to Ultra, then the manual eraser, then manual correction by expert staff.

Pricing

There are monthly, quarterly, and yearly subscriptions (Basic and Pro), and one-time credit packs. Each processed image uses credits: Standard 1, Color 3, Ultra 5, and manual correction by expert staff 8 (checked on the official pricing page in October 2026).

The web version is priced in US dollars and paid via Stripe (credit card) or PayPal. The pricing page does not state whether tax is included, and the terms of service make users responsible for applicable taxes. The yen amounts are the in-app purchase prices shown on the App Store (Japan) for the iPhone app.

The API is priced separately from the web plans. The API page lists API-only packages: Starter $99 (500 credits, valid 3 months), Popular $349 (5,000 credits, valid 6 months), Business $749 (15,000 credits, valid 1 year), and Enterprise $1,999 (50,000 credits, valid 1 year). Images sent via the API must be under 5MB with the longest side under 4,000px.

Pros and Cons

Pros

• A tool focused on removing handwriting, with steps to choose from: keeping color, handling difficult pages, and manual work by staff
• It tells printed text apart from writing, so it takes less effort than eraser-style image editors where you trace the area yourself
• The same credits work on the web and in the mobile apps, and both the site and the apps can be shown in Japanese
• You can start with Basic at $3.9 per month, or choose non-expiring one-time packs if you only use it occasionally

Cons

• The free allowance is only the 3 sign-up credits (plus credits from ads and referrals in the app), which run out quickly with Color or Ultra
• The terms of service say not to upload images containing confidential personal information. Before processing answer sheets with student names and scores, or documents with personal data, you need to check against your school's or company's rules
• Dense writing over printed text, or blurry or heavily shadowed photos, can leave strokes behind or damage text (an official caveat)
• Web prices are in US dollars and do not match the yen prices on the App Store by exchange rate
• As of October 2026, the App Store (Japan) has only 3 ratings (average 2.3), so there is little to go on for its reputation in Japan

Reputation and User Feedback

In a February 2026 post, the official blog says the service has served more than 100,000 customers in a little over two years. On the App Store (Japan), there were 3 ratings (average 2.3) as of October 2026, too few to read a trend. The company has warned that fake apps using the same name have appeared in app stores, and asks users to install the app from the "Download app" link on the official website.

How Files Are Handled

According to the official privacy policy and product pages, uploaded files are used only for processing, are deleted automatically after processing, and are not used to train AI models. Files may be held temporarily during processing or failure recovery. Transfers are encrypted, and card details are handled by Stripe and PayPal.

On the other hand, the terms of service state that image processing operations are logged to detect violations. Users without an API plan may use the service only manually through the website or apps, and automated scripts are prohibited. For high-volume business processing, use the API. There is no guarantee of speed or uptime (SLA); if you need one, the company asks that it be agreed separately in writing.

The Company Behind It

The operator is Shenzhen Liwa Software Technology Co., Ltd. in Shenzhen, China. The same company name appears on the official product facts page, in the terms of service, and as the seller on the App Store (Japan). The developer name shown on Google Play is Liwa Software Limited, which the official site explains is its display name on Google Play. Support is available by email (service@removehandwriting.com, replies within 24 hours) and WhatsApp (weekdays 9:00–18:00 GMT).

How It Differs from Other Image and Document Tools

RemoveHandwriting specializes in identifying and removing only handwritten marks while keeping the printed content. Its role differs from image editors where you trace what to erase, and from tools that rebuild documents into another form.

Columns for other products reflect the content on each product page as of the time it was checked.

To remove people or objects from photos, Magic Eraser is a good fit; to handle photo editing and design in one place, consider Fotor. If you want to turn a scanned document in a foreign language into Japanese while keeping its layout, Reglyph is the one to compare. If you want to check how to solve the problems on a worksheet, you can also combine it with the math explanation app Photomath. For the task itself of removing writing while keeping the printed content, RemoveHandwriting is the right fit.
