PDF guides
Split a PDF or extract pages: choose the right operation
Create separate chapter files or one shorter PDF, with clear page-range examples and checks that prevent missing pages.
PDF guides
Reduce PDF file size without overlooking the quality trade-off
Learn when raster PDF compression is useful, which settings to test, and why a smaller file can lose searchable text and forms.
PDF guides
Convert JPG images to one PDF with the right page size
Turn photos or screenshots into a PDF while controlling order, paper size and the difference between image pages and searchable text.
PDF guides
Convert PDF pages to JPG or PNG without screenshotting
Export complete PDF pages as images, choose a sensible resolution and understand why page rendering is different from extracting embedded photos.
PDF guides
Extract text from a PDF: text layers, scans and reading order
Save existing PDF text as UTF-8 TXT and learn how to recognize a scanned document that needs OCR instead.
Images & design
JPG, PNG or WebP: which image format should you choose?
Choose an image format based on photographs, sharp graphics, transparency and the destination’s requirements, rather than file size alone.
Images & design
Resize an image without stretching faces or objects
Understand aspect ratio, fitting inside a box and cropping so that the final image has useful dimensions without distorted proportions.
Images & design
Compress an image to a target size without missing upload requirements
Prepare an image for a KB limit while checking format, minimum dimensions and the detail that compression can remove.
Images & design
Remove an image background in your browser and check the edges
Create a transparent PNG from a clear subject, understand the first model download and recognize where automatic cutouts need a closer look.
Images & design
Convert HEIC to JPG without losing track of the original
Make an iPhone photo easier to share, choose sensible export settings, and check the result before uploading it to a form.
Images & design
Crop a photo for a form: shape first, pixels second
Prepare a square or rectangular photo with a controlled crop, then resize and compress without stretching the subject.
Images & design
Build a useful color palette from a photograph
Extract representative HEX colors, recover a missing accent with a crop, and test the combinations before using them in a design.
Code & data
Create a QR code that still scans after you print it
Choose a stable destination, preserve the white margin, and test the downloaded QR at the size and distance people will actually use.
Code & data
Base64 is not encryption: encode and decode text correctly
Understand what Base64 changes, choose the right alphabet, and avoid mistaking readable encoding for protection of passwords or tokens.
Code & data
URL encode and decode: keep values separate from addresses
Choose component or complete-URL mode, understand plus signs, and avoid changing a link’s structure by decoding it twice.
Code & data
Format JSON without changing the data you meant to keep
Make a JSON document readable while understanding duplicate keys, large numeric identifiers and the difference between syntax and schema.
Code & data
Convert CSV and JSON while keeping identifiers intact
Handle headers, quoted cells, leading zeros and spreadsheet formulas, and understand why a CSV–JSON round trip is not always reversible.
Writing & text
Why two word counters can give different results
Choose a word and character definition that matches your task, especially for emoji, combined characters and writing without spaces.
Dates & planning
Calendar days or business days? Count the interval you mean
Choose inclusive or elapsed counting, enter holidays explicitly, and avoid confusing a date-only calculation with elapsed working hours.

Local file processing: privacy, PDF and image limits
Follow a file from selection to download, distinguish document processing from network traffic, and plan PDF and image batches within the actual limits.
PDF guides
Browser tools or desktop software: choose by the job
Decide when a local browser tool is enough and when OCR, signatures, secure redaction, large batches or offline work need a different workflow.
