What is iSomor?
iSomor is an online document workspace built around translation, reading, comparison, checking and saving.
It processes complete PDFs rather than returning text disconnected from its pages, retaining relationships among page numbers, paragraphs, tables, charts, formulas and other page elements.
Within the same workflow, users can:
- upload and translate text-based PDFs;
- choose the complete document or specific pages;
- view each original and translated page;
- check terms, names, numbers and page structure;
- download translated-only PDFs;
- download bilingual PDFs arranged horizontally or vertically;
- organize PDFs, images and text using browser-local tools;
- access document processing through compatible AI Agents or an API.
Who is iSomor for, and which documents does it cover?
iSomor serves individuals and organizations worldwide that need to read, translate, check, organize or deliver multilingual PDFs. It is not restricted to one profession or industry, covering research, engineering, manufacturing, healthcare, education, business, finance, law, administration and general office work.
Representative documents include:
- Papers and research reports: retain relationships between two-column text, technical terms, formulas, charts, captions and references.
- Technical manuals and instructions: compare models, parameters, units, steps, part names and warnings.
- Medical and health documents: read papers, research materials, instructions and PDFs containing specialist terminology.
- Engineering and manufacturing documents: translate equipment manuals, specifications, product materials and engineering reports.
- Business and financial documents: retain tables, charts, amounts, ratios and time information.
- Contracts, forms and certificates: check names, dates, numbers, organizations, fields and clauses.
- Education and training materials: read textbooks, course materials, handouts and multilingual learning documents.
- General office documents: process reports, manuals and internal materials requiring page structure.
These uses share the same core capabilities: complete PDF translation, layout preservation where possible, original-to-translation correspondence and PDFs that remain available for reading, checking or saving.

How does iSomor translate PDFs?
iSomor uses AI to translate recognizable, selectable PDF text in the context of its paragraphs and page structure.
Compared with copying separate passages, complete-document processing helps:
- retain heading and body-text hierarchy;
- interpret long sentences and technical vocabulary in context;
- keep table text connected to its rows and columns;
- keep chart descriptions associated with their charts;
- connect formula explanations to the original formulas;
- trace pages, paragraphs and document structure.
iSomor aims to place translated text back in the corresponding page areas, retaining reading order and information structure.
The current limit is one text-based PDF per upload, up to 300 MiB and 1,500 pages.
How does iSomor preserve PDF layout?
Translation changes text length. Simply replacing text can cause paragraph overflow, displaced tables, obscured headings or page elements moving out of position.
iSomor rearranges translated text using original text areas and page structure, aiming to preserve:
- page dimensions and page order;
- heading and body-text hierarchy;
- single-column or multi-column reading order;
- tables and cell relationships;
- image, chart and caption positions;
- relationships between formulas, numbering and explanations;
- headers, footers and paragraph boundaries.
The result remains a complete PDF rather than disconnected plain text.
How does original-and-translation comparison work?
iSomor retains the original PDF and associates each source page with its translated page.
Readers can return to the original while reading, giving them direct evidence for checking names, technical terms, numbers, amounts, units, formulas and table data.
| Output format | Content |
|---|---|
| Translated-only PDF | Translated pages for continuous reading |
| Side-by-side PDF | Original and translated pages next to each other |
| Vertically stacked PDF | Original and translated pages above and below each other |
Bilingual PDFs keep source evidence and AI translation in one file, reducing repeated file switching and searches for corresponding page numbers.
Which languages does iSomor support?
The website supports 92 target languages and regional variants; its interface supports 12 languages.

Which browser-local tools does iSomor provide?
Alongside cloud translation, iSomor offers seven tools that process files in the browser on the user’s device without using translation credits.
| Local tool | Capability |
|---|---|
| Images to PDF | Arrange JPG or PNG images and combine them into a PDF |
| PDF to images | Export PDF pages as PNG or JPG |
| Merge PDF | Combine PDFs in a chosen order |
| Split PDF | Select pages to create a new PDF or individual page files |
| Extract PDF text | Extract text from PDFs with a text layer |
| Text cleanup | Tidy line breaks, spaces and broken words in copied text |
| Logo background removal | Remove a selected background color and export a transparent PNG |
These tools are independent of cloud translation. Organize files first, then decide whether to translate the PDF.
Can iSomor organize photos?
The upload entry supports organizing JPG, PNG and HEIC photos in the browser:
- add several photos at once;
- view thumbnails;
- reorder photos;
- remove unwanted photos;
- combine them into a PDF with one photo per page;
- preview the generated PDF before continuing.
Organization and PDF assembly happen locally. This step does not directly upload the original photos; subsequent processing handles the PDF created from them.
Can I use iSomor through an AI Agent?
Yes. Connect iSomor MCP and authorize your account to let compatible AI Agents call iSomor PDF tools as part of an Agent workflow, rather than only operating the website manually.
iSomor also offers API access. API credentials are issued separately after review.
MCP and API translation currently targets English and Chinese. Website translation and these interfaces have different access methods and language coverage.
Can I use iSomor for free?
iSomor provides free previews and a free account allowance:
- guests can preview translations of the first 2 PDF pages;
- further translation or downloading requires signing in to a verified account;
- verified accounts are topped up to 20 free credits every 7 days;
- each text-based PDF page translated costs 1 credit;
- unused periodic free allowance does not accumulate;
- the upload page shows the actual available allowance.
Preview the translation, structure and page correspondence before deciding whether to process the complete document.
How does iSomor handle documents and privacy?
Cloud translation processes uploaded PDFs and sends text requiring translation to an AI translation service.
Originals and results are stored privately and provided to authorized users through temporary links. Browser-local tools process selected files on the user’s device without submitting file content to cloud tool endpoints.
Cloud translation and local tools handle data differently. Before uploading personal, business or other sensitive information, read the iSomor privacy policy.
