Why convert WK3 to PNG?
A WK3 file is a Lotus 1-2-3 Release 3 worksheet, the version that introduced several sheets stacked in one file. The PNG shows the worksheet's cells as LibreOffice Calc prints them, with calculated values, number formats and text laid out in rows and columns, sheet by sheet.
PNG keeps every pixel exactly as rendered, so text, thin lines and flat colours stay crisp, and transparency is preserved.
Frequently Asked Questions
How do I convert WK3 to PNG?
Drop your WK3 file above and press Convert. Our servers open the Lotus worksheet in LibreOffice Calc, print every sheet to a PDF and render each page as an image. The result is saved as a lossless PNG, ready to download.
Is every sheet of a multi-sheet WK3 included in the PNG?
Yes. Release 3 files can hold several sheets, and each one is printed in turn, so all of them appear in the PNG pages.
Do Lotus @ functions in a WK3 show their results in the PNG?
Yes. LibreOffice Calc reads Lotus formulas such as @SUM and @AVG, and each cell prints its calculated value.
What happens when a WK3 file fills several PNG pages?
Each page is rendered at 144 dpi and saved as its own PNG image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one PNG file.
Why is PNG a good fit for a WK3 conversion?
PNG is lossless: the image keeps every rendered pixel with no compression artefacts, which keeps small text, table lines and drawings perfectly sharp.
Is my .wk3 file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
