What happens when you convert XLS to PNG
- The XLS is opened by LibreOffice, the open-source office suite, on our conversion server, laid out exactly as it would print, and each page is then drawn as an image by MuPDF at 150 dpi, the resolution most documents are printed at.
- A one-page XLS gives a single PNG; a longer one comes back as a ZIP file with one PNG per page, named page-01.png, page-02.png and so on, for up to 100 pages.
- At 150 dpi, an A4 page becomes about 1240 by 1750 pixels. The longest side is capped at 6,000 pixels.
- PNG is lossless, so text and lines stay exactly as crisp as the page rendered them.
- Sheets are printed across as many pages as they need, following their print area and page setup, so a wide sheet may be split across pages.
- Where the file uses a font our server does not have, a metric-compatible one is used instead: Carlito for Calibri, Caladea for Cambria and Liberation fonts for Arial, Times New Roman and Courier New, so lines break where they did. Unusual or decorative fonts may look different.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.
How to convert XLS to PNG online
- Press "Choose XLS files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to PNG". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each PNG with its download button. Our server has already deleted both your XLS and the PNG by then.
Why convert XLS to PNG?
XLS files usually come from older Excel files and systems that still export the legacy format. People convert them to PNG to share a page as a picture: in a chat or a social post, on a website, in a presentation, or in an upload form that only accepts images. PNG opens on every phone and computer without an office program.
How to convert XLS to PNG on Windows, Mac, iPhone and Android
On Windows
Open this page in Chrome, Edge or Firefox, drag your XLS files in from File Explorer, and press Convert. Each PNG is saved to your Downloads folder.
On a Mac
Safari, Chrome and Firefox all work. Drag the XLS files from Finder onto the drop zone and the PNG files land in Downloads.

Best settings for XLS to PNG
There are no settings: every page is rendered at 150 dpi, the longest side is capped at 6,000 pixels, and at most the first 100 pages are converted.
To get one page only, save just that page as its own file first, or pick the image you want out of the ZIP. For a document you will print or send, PDF keeps the text sharp at any size and selectable.

About XLS and PNG files
What is an XLS file?
XLS is the binary Excel format used before 2007. It is limited to 65,536 rows and 256 columns per sheet, far fewer than XLSX allows.
What is a PNG file?
PNG compresses without losing a single pixel, so screenshots and text stay razor sharp, but a photograph saved as PNG is often three to five times the size of the same photo as JPG.
XLS to PNG not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Compress the images inside the file, or split it, and try again.
- "The conversion took too long and was stopped." Very long or complex files can pass the 90 second limit. Split the file and convert the parts.
- The file will not convert. It may be password protected, damaged, or saved in a newer or unusual version of the format.
Convert XLS to PNG from the command line
LibreOffice and Poppler do the same on your own computer: the first command makes a PDF, the second writes one image per page.
soffice --headless --convert-to pdf input.xls
pdftoppm -r 150 -png input.pdf pageConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
XLS to PNG converter FAQ
Will I lose quality converting XLS to PNG?
The images are sharp enough to read on any screen: 150 dpi is the resolution most documents are printed at. PNG keeps every pixel exact. The text in an image can no longer be selected or searched.
Why is the PNG a different size from the XLS?
Each PNG holds a full page of pixels, so the images together are usually larger than the XLS, which stores text and drawing instructions. PNG pages of mostly text stay small; pages full of photos grow large.
Are my XLS files uploaded?
Yes, for this conversion. A faithful XLS to PNG conversion needs LibreOffice and MuPDF, two open-source tools, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the PNG as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several XLS files to PNG at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a PNG file?
PNG opens in every browser and image viewer. PNG is common for screenshots, logos, diagrams and anything with transparency.
Is this XLS to PNG converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert XLS to PNG on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the PNG is saved to your Downloads folder.
