Instead of returning a wall of plain text, it rebuilds the translated content inside the original page structure — headers, columns, tables and image captions stay where they were. PDF, Word, Excel, PowerPoint and image files such as PNG, JPG and WEBP are all supported, so contracts, research papers, product manuals and design drawings come back in a form you can still use. The service pairs a layout engine with selectable AI translation engines, which means you can pick a model per job and watch your usage. OCR handles scanned pages and text baked into images, and every result can be reviewed in a bilingual view that places the translation under or beside the source. A built-in editor lets you fix terminology, and a glossary feature keeps recurring industry terms consistent across long projects. For collaborators and developers there is also a batch translation API. Beyond the core document flow, Doclingo ships a browser extension for Chrome and Edge that translates WhatsApp and Telegram Web messages in place, a dedicated image translation mode with strict-layout and readability-first options, and a document chat that lets you ask questions about an uploaded file. There is a genuinely free tier with no signup required for standard translations, plus a paid PDF Pro track aimed at high-fidelity restorations and heavy OCR workloads, so the tool serves both occasional students and professional localization teams. **Pricing & Plans:** Freemium-style with a no-signup free tier for standard document translation and a paid 'PDF Pro' tier for high-fidelity restoration, advanced OCR and larger volumes; an enterprise/API option exists. Check the site for current plan limits. - **Layout-preserving translation:** Translated text is redrawn into the original document structure, keeping columns, tables, headings and images in place instead of producing a stripped-down text dump. - **OCR for scans and images:** Recognises text in scanned PDFs, screenshots, photos, menus and posters, then translates it and puts it back into the image at the same position, size and colour. - **Bilingual side-by-side output:** Read the source and the translation together, which makes reviewing terminology in contracts and academic papers far faster than flipping between files. - **Wide format and language support:** Handles PDF, Word, Excel, PowerPoint and common image formats across 90+ languages, with batch processing for multiple files at once. - **Browser extension for chat translation:** The Chrome/Edge extension translates WhatsApp Web and Telegram Web messages inline and can translate your own replies before sending them. **Strengths:** Layout and formatting are genuinely preserved, which is the main weakness of most free translators; OCR handles scanned documents and text inside images, not just clean digital files; Free tier works without creating an account, lowering the barrier to trying it; Extras like bilingual view, glossary, online editing and chat translation make it a workspace rather than a one-shot converter **Limitations:** Very large or complex files can take a while to process, and heavy OCR use pushes you toward the paid tier; The browser extension is desktop-only and cannot be installed on phones; Translation quality still varies by language pair and by which AI engine you select [Profile (Markdown)](https://openaitools.app/tool/doclingo.md) ## LightPDF LightPDF positions itself as an all-in-one document workspace rather than a single-purpose converter. The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices. The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator. Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request. **Pricing & Plans:** Freemium. A free plan covers basic PDF tools with a 10MB file cap; paid plans start around $5.99/month, with a yearly tier and a one-time lifetime option. AI features consume monthly credits that differ by plan. - **AI document agent and chat:** Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos. - **Layout-preserving translation:** Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact. - **AI data extraction to spreadsheets:** Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically. - **Full PDF editing and conversion suite:** Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate. - **Cross-platform access:** One account works on web, Windows, Mac, iOS and Android, so documents and paid features follow you between devices. **Strengths:** Very broad toolkit that covers both everyday PDF chores and advanced AI document tasks; Free tier is usable for light jobs, and the paid plans are cheaper than many competing PDF editors; Layout-preserving translation and AI data extraction handle scanned documents that trip up simpler tools; One subscription covers five platforms, including desktop and mobile apps **Limitations:** Free plan caps files at 10MB and adds watermarks on some outputs; AI features run on a credit system, so heavy usage means top-ups or a higher tier; Advanced AI operations like text editing or logo removal consume credits quickly [Profile (Markdown)](https://openaitools.app/tool/lightpdf-com.md) ## Frequently Asked Questions ### How do Doclingo and LightPDF compare in monthly traffic?
