Try a real file task with a sample.
Use these original MyFileNest files to explore the tools before choosing your own documents. Each walkthrough gives you an input, exact settings and an expected result you can inspect. You do not need an account.
The files are generated demonstration material, with no customer data. Expected dimensions and page contents follow from the supplied inputs; they are not speed, quality or compression benchmarks.
Flatten a transparent PNG onto white
An upload form accepts JPG, but your graphic has a transparent border. What happens to those pixels?
960 × 640 pixels · 41,806 bytes
Try it
- Download the sample PNG and open PNG to JPG.
- Choose the sample, set the background to white (#ffffff), and keep the original dimensions.
- Convert, download the JPG, and open it in an image viewer.
Expected result
The JPG should be 960 × 640 pixels. Its 80-pixel outer border should be solid white. The orange circle, gradient and dark bars should remain visible. JPG cannot retain the sample’s transparency.
What to inspect and why
Look at the narrow bars and circle edge at 100% zoom. JPG may add edge artifacts. A smaller file is not automatically a better result for this graphic; retain the PNG when transparency or sharp edges matter.
Resize a graphic without stretching it
You need a 480-pixel-wide preview. How do you check that resizing preserved the shape?
960 × 640 pixels · PNG
Try it
- Download the sample and open Image Resizer.
- Keep the aspect ratio locked, set width to 480 pixels, and choose PNG to retain transparency.
- Resize and download the result. Check its dimensions in your image viewer’s properties.
Expected result
The output should be 480 × 320 pixels. The orange circle should remain round, the transparent border should be 40 pixels wide, and the full graphic should fit without a crop.
What to inspect and why
The original ratio is 960 ÷ 640 = 1.5. Dividing 480 by 1.5 gives a height of 320. The pixel count drops from 614,400 to 153,600, but the encoded byte size does not have to drop by exactly 75%.
Keep just the middle page of a PDF
A recipient needs one page from a longer document. Can you verify that you sent the right page?
3 numbered pages · 2,316 bytes
Try it
- Download the three-page PDF and open Extract PDF Pages.
- Choose the sample, select the custom page option, and enter 2.
- Extract and download the PDF. Open it and check the page count and text.
Expected result
The output should contain one page headed “SECOND - Keep this page”. Its body should still say “Original page 2 of 3” and “MFN-EXAMPLE-2026”. The PDF viewer will number the new document’s only page as 1.
What to inspect and why
Select and copy the reference text to confirm it remains selectable. The FIRST and THIRD pages should be absent. This simple file does not test form preservation, digital signatures, encryption or scanned-document behavior.
When your own file behaves differently
Try the small sample first. If it works but your source fails, compare the format, dimensions, page count and whether the PDF has selectable text. A sample passing does not establish support for every file. On a phone, begin with one file to avoid using too much memory.
Keep the source and inspect every downloaded result. Report a problem with the tool name, browser, chosen settings and the message you saw. Do not attach confidential documents or paste private file contents.
