USE EVERY TOOL.
WITHOUT GUESSING.
Each tool is independent. Choose the task you need, follow the short workflow below, and keep your work on your device whenever local processing is available.
PDF MERGE
Add two or more PDF files, arrange them in the required order, remove anything you do not need, and select the merge action.
- Files are read in browser memory.
- The merged result is downloaded to your device.
- Closing the page clears the working file list.
PDF SPLIT
Add one PDF, review the three-column page preview, and select the cut markers between pages. Confirm the split to download the resulting documents.
- Cut markers appear before, between, and after pages.
- Page previews help confirm the correct boundaries.
- Multiple outputs are packaged for convenient download.
PDF PAGE ORGANIZER
Add one PDF, drag page cards into a new order, rotate or remove pages, and select any pages you want to extract.
- SAVE PDF keeps every visible page in its displayed order.
- EXTRACT SELECTED creates a PDF containing only selected pages.
- Keep the original document until you have checked the new file.
PDF TO IMAGES
Add one PDF, optionally enter a page range such as 1-3, 5, and choose PNG or JPEG plus a rendering scale.
- Selected pages are packaged in a ZIP file.
- A higher scale produces larger, sharper images and uses more memory.
- Encrypted or damaged PDFs may not open.
IMAGES TO PDF
Add JPG, PNG, or WebP images, put them in order, choose a page size and margin, and create one PDF.
- Match each image preserves its natural page proportions.
- A4 and US Letter fit each image inside a standard portrait page.
- Very large images may use substantial browser memory.
IMAGE TOOLKIT
Add one JPG, PNG, or WebP image, enter output dimensions, choose a format and quality, and download the result.
- Keep aspect ratio prevents accidental stretching.
- Quality affects JPEG and WebP output; PNG is lossless.
- JPEG output replaces transparent areas with white.
FILE HASH CHECKER
Choose a file and an algorithm. Compare the calculated hexadecimal value with a checksum supplied by the file publisher.
- SHA-256 is the usual default for modern checksum verification.
- A matching hash supports file-integrity checking but does not by itself prove a file is safe.
- Changing even one byte produces a different hash.
QR CODE GENERATOR
Enter text or a URL, choose an error-correction level and image size, then download the PNG.
- Higher error correction can improve resilience but makes the code denser.
- Test the QR code with more than one device before printing or publishing it.
- Do not encode secrets in a QR code intended for public display.
FOCUS TIMER
Choose a preset or enter a custom duration, select START FOCUS, and keep the tab open while you work.
- Space starts or pauses the timer.
- R resets the current session.
- The selected timer state is stored in this browser so a refresh does not immediately erase it.
PATH STUDIO
Open Path Studio on a desktop or laptop with a screen at least 1080 pixels wide. Use PEN to place anchors, hold Alt while dragging to create curves, and use SELECT to move anchors, handles, images, or complete paths.
- Drag two open endpoints together to join paths.
- Add image layers and adjust their opacity in Properties.
- SAVE PROJECT creates a local .pathwork file that can be reopened later.
- EXPORT PNG creates a flattened image of the canvas.
MULTI CALCULATOR
Choose arithmetic, PERCENT, DISCOUNT, or TIP / SPLIT. Enter the requested values and the result updates immediately with a short calculation summary.
- Arithmetic mode adds, subtracts, multiplies, or divides two values.
- PERCENT calculates a percent of a number or the percentage change between two values.
- DISCOUNT removes the entered discount before applying sales tax.
- TIP / SPLIT adds a tip and divides the total among a whole number of people.
- Review local tax, service-charge, and rounding rules before relying on a result.
