your situation	Recommended practices	reason
The pictures are clear and the text is printed horizontally	Directly upload the original image or screenshot	Clear text boundaries, more stable recognition and translation
Photos are skewed, text is small or reflective	Crop, straighten, and enlarge before uploading	Reduce missing words and typos
For some mobile phone systems, the pictures are in the photo album	First save to a file or album, then select it in the browser	The browser needs to be able to access this image
Just want to understand the general idea	Select translation only	Pages are cleaner and faster to read
Need to save or check against the original text	Choose bilingual comparison	The original text and the translation are side by side for easy sentence-by-sentence comparison.

Before you start: Confirm these points first

Taking half a minute to check before taking action can save you the trouble of repeated retransmissions.

Is the picture and text clear? Blurred, reflective or blocked words are prone to errors in recognition. Zoom in and take a look. If you can clearly identify each word, upload it.
Is the picture a screenshot or a photo? Screenshots usually have neater text boundaries; photos often have perspective distortion and need to be cropped and straightened first.
Whether the mobile phone is connected to the Internet. Both uploading and translation require a network connection, and the wait may take a long time in a weak network environment. It is recommended to move to a stable Wi-Fi or a place with a good signal.
Whether the picture contains private information. Contents such as ID number, bank card number, address, etc. must be blocked by the editing function of the mobile phone before uploading, and then translated.
Do you want a translation or a comparison? This determines how to choose the fifth step. Thinking it through in advance can save you rework.

Steps to translate image text in mobile browser

Save Image. After taking a screenshot or taking a photo, zoom in to make sure the text can be seen clearly. If the text is skewed, crop out the irrelevant parts first and keep only the text area you want to translate.
Open the web version. Use your mobile browser to visit omnidoc.top and enter the translation page. When the page is crowded, you can view it horizontally or switch to the computer version of the page in the browser menu.
Select image file. Click the upload area, find the picture you just saved from the album or file and select it.
Confirm translation direction. Check whether the language settings on the page are correct, such as translating English into Chinese to avoid waiting in vain if the direction is reversed.
Select the output method. If you just want to understand, choose translation only; if you need to compare with the original text, choose bilingual comparison.
Submit and wait. Submit after confirming that the information is correct. Do not close the page until the translation is completed. The larger the image, the longer the waiting time is usually.
Download results. Save the translation to your mobile phone for easy review at any time, or send it to yourself for your own files.
Restart when text is missed in translation. If you find that a certain section is not translated, go back to the first step, crop out that section and upload it separately. It is usually more accurate than re-transmitting the entire picture.

Several common situations on some mobile phone systems

Picture is in the album: First confirm that the photo has been saved in the album. You can select it from the album when uploading it through the browser. There is no need to download it elsewhere.
Pictures come from chat history or web pages: Long press or click to save to the album before uploading to avoid getting only thumbnails.
Upload directly after taking a screenshot: The screenshot will be saved in the album, just like the operation of ordinary photos.
File in File App: If the image is stored in File App, just select the corresponding file location when uploading.

Check each item after completion

Both machine translation and image recognition may make mistakes. After getting the results, check them according to the table below.

Check items	How to see it	What should you do if there's a problem?
Whether the text is complete	Compare with the original image line by line to see if any entire line is missing	Cropping only keeps the text area and retransmits it separately
Numbers and units	Check whether the price, date, and size match the original images	Return to the original image for manual correction
Personal names, brands, and proper nouns	Whether the original text is preserved or the translation is consistent before and after	Manually unify before use
Layout order	Check whether the multi-column or table content is misaligned	Upload in sections, or manually organize according to the original image order
Key content	Contract terms, instructions, drug usage, etc	Experts, please double-check; don't rely solely on machine translation

❓ Frequently Asked Questions (FAQ)

1. If the photo taken by your phone is crooked, should you fix it first?

It is recommended to crop and straighten before uploading. Crooked text affects recognition, and translations often result in line errors or missing words.

2. What is the difference between image translation and full PDF translation?

Images usually contain only one page or a paragraph of text, making them suitable for quickly grasping parts of the content. The entire PDF is longer and requires attention to layout and page numbers, so it can be handled separately by document type.

3. What if you can't find pictures on some phone systems?

First, make sure the image has been saved to your album or file app. When uploading, switch to the corresponding location in the browser's selection screen, and you can usually find it.

4. What to do if there is private information in the screenshot?

Before uploading, use the phone's built-in editing function to cover your ID number, bank card number, etc., and then translate to prevent sensitive information from being uploaded.

5. Can the translated text be used directly?

Daily reading comprehension is usually sufficient. When used for contracts, documents, medical documents, or official documents, each item must be checked against the original drawings; important content should be checked manually.
