For English and ESL teachers

Placement and progress checks

The free English level test gives each student an estimated CEFR level from A1 to C2 in 30 multiple-choice questions — five at each level, drawn at random, so two students side by side won’t see the same paper. It’s a quick way to group a new class or check where a new arrival should start. Treat it as a placement guide rather than a formal assessment: it measures grammar and vocabulary knowledge, not speaking or writing.

Lessons to set as homework

Every lesson in the A1, A2, B1, B2, C1 and C2 courses has its own web address, so you can set a specific lesson by sharing its link. Each one explains a single topic with examples and ends with exercises that mark themselves, so students get instant feedback without adding to your marking pile. The grammar library is useful for quick “look it up” homework, and the IELTS and TOEFL courses suit exam classes.

Worksheets and handouts

• Merge PDF — combine a reading text, questions and answer key into one handout, taking only the pages you need from each file.
• Delete, reorder and rotate pages — tidy up scanned textbook pages.
• Split PDF and Extract pages — pull one unit out of a long workbook.
• Edit PDF — white-out answers on a worksheet, add instructions or correct a typo.
• Add page numbers — so “turn to page 4” works for everyone.
• Watermark PDF — mark drafts or “Answer key — teacher copy”.
• Compress PDF — get big files under your learning platform’s upload limit.

Copyright still applies to material you copy from textbooks — follow your school’s licensing rules.

QR codes in the classroom

A QR code on a slide or poster gets thirty students to the same page in seconds. The QR Code Generator makes static codes that never expire and needs no account.

• Station activities: a code at each table linking to a different reading, video or lesson.
• Homework: a code on the board or worksheet linking to that week’s lesson.
• Classroom Wi-Fi for visitors, with the Wi-Fi QR Code Generator (where school policy allows).
• Parent information: a code on newsletters linking to the class page or a booking form.

Writing tasks and word limits

The Word Counter shows words, characters, sentences and paragraphs, plus reading and speaking time — handy for setting a two-minute speech (roughly 260–300 words) as well as checking essays. Students can paste their draft in themselves; nothing is saved or sent anywhere.

Images for slides and worksheets

• Crop and resize pictures so they fit a worksheet layout.
• Remove a plain background from photos of objects for vocabulary flashcards.
• Blur or pixelate students’ faces and names before sharing photos of class work, and strip location data with the EXIF Remover.
• Compress images so slide decks aren’t too large to share.

A quick routine many teachers use: at the end of term, merge each student’s marked work into one PDF per student, number the pages and compress it — a tidy portfolio for parent meetings or reports.

Maths and science helpers

• Percentage and average calculators, with working shown — useful for checking marks.
• 123 unit converters, from length and temperature to pressure and energy.

Why it works in schools

• No accounts — no student emails collected, no passwords to reset.
• Files stay on the device — PDF and image tools process files in the browser, which helps with student-privacy obligations.
• Runs on school hardware — Chromebooks, iPads, interactive whiteboards and staffroom PCs, with nothing to install.
