Keep the original
Save a copy of the original image. Start with the sample PNG if you only want to learn the controls.
Resize only when needed
Open Image Resizer and set the dimensions required by your website or platform. Keep the aspect ratio unless you deliberately want a different shape. Making a small image larger does not recover missing detail.
Compress a copy
Download the resized image and open it in Image Compressor. Try a moderate quality setting first, then compare the result with the source at normal viewing size.
Choose an appropriate format
Use JPEG for many photographs, PNG when transparency or crisp flat graphics matter, and WebP when your destination accepts it. Convert a copy in Image Format Converter.
Check the downloaded result
Open the final download. Confirm its dimensions, appearance and file size before replacing the original or uploading it elsewhere.

Combine PDFs into a tidy document

Merge in a deliberate order, review the result, and add page numbers last.

Prepare the inputs
Keep your original PDFs. Open them first so you know their page counts and whether any are password-protected. The downloadable two-page sample is useful for a small trial.
Arrange the documents
Open Merge PDF Online, add the source files and arrange them in the required order. Check the list before generating the merged PDF.
Download and inspect
Open the downloaded PDF and check the first and last page of each source document. Confirm the total number of pages and the reading order.
Correct sideways pages
If needed, use Rotate PDF Pages on the merged copy. Review the saved result rather than relying only on the on-page preview.
Number the final bundle
Use Add Page Numbers to PDF after merging. Choose a position that does not cover existing content, then inspect the final download.

Clean a CSV before splitting it

Remove repeated records, put rows in order, then create smaller files.

Start with a copy
Keep the original CSV unchanged. Make sure it has one header row and consistent columns. Fields containing commas or line breaks need CSV quoting.
Choose what counts as a duplicate
Open CSV Duplicate Row Remover. Use all fields for exact duplicate rows or a key column when that fits your data. Two rows sharing a name are not always the same person.
Review before sorting
Download or copy the cleaned output. Compare a few records, especially blank cells, quoted text and identifiers with leading zeros.
Sort by the right column
Open CSV Sorter. Enter the exact header name and choose numeric sorting only when that column contains actual quantities. Keep account codes and similar identifiers as text.
Split and verify
Open CSV Row Splitter and choose the row count per part. Download the generated files. Check that headers are repeated and that the total data-row count matches the cleaned source.

Use separate documents for a proposed price, a bill and a recorded payment.

Estimate the work
Use Project Quote Calculator to account for the costs, contingency and deposit you choose. Treat the calculation as planning, then review the assumptions.
Prepare a quotation
Open Quotation Maker and enter your actual scope, line items and prices. Review client details, dates, totals and any conditions before sharing the draft.
Create the invoice when appropriate
Use Invoice Generator when you need to bill for agreed work. Keep quotation and invoice references distinct so the documents are easy to track.
Record a payment accurately
Use Receipt Maker only for a payment you can confirm. Enter the amount, date and payment reference from your own records. A generated receipt does not verify a payment.
Review and keep a copy
Inspect the printable preview and the browser's print settings. These tools prepare documents; they do not send invoices, collect money or establish that a client agreed to terms.
