Questions
- How to convert PNG to JPG without surprisesHow to convert a PNG to JPG or WebP, why a transparent background turns into a color, and which format to choose for product photos.
- I saved an image from a website and it is a WebP that my programs will not open. How do I turn it into a JPG?Images saved from websites often arrive as WebP, which some programs refuse. Re-encode them as genuine JPGs at a quality you choose, with the same name, in your browser.
- How do I convert a transparent WebP logo to PNG and keep the transparency?Got a WebP logo with a transparent background and need a PNG? Choose PNG in the converter and the transparency survives with no extra loss. Expect a bigger file.
- Does converting a JPG to PNG improve its quality, and why is the PNG so much bigger?Turning a JPG into a PNG does not raise its quality: it freezes the existing flaws and multiplies the size. Why, with numbers, and when PNG still makes sense.
- Should I convert my website's JPGs to WebP, and at what quality?WebP usually gives smaller files that look much the same, but before switching a whole site check that your platform takes it, test quality on a sample and compare sizes.
- Is WebP a lighter alternative to PNG for a see-through logo on my website?Both formats keep transparency. WebP is usually much lighter but lossy; PNG is exact and accepted everywhere. When to use each for your store logo.
- My image ends in .jpg but the site says the format is not supported. What is going on?Many images saved from the web are named .jpg but are WebP inside. How to spot it in the format converter and get a genuine JPEG the site accepts.
- I have a mix of PNG, WebP and JPG images. How do I turn them all into JPG in one go?Add up to 30 images in any mix and choose JPEG: PNG and WebP convert, JPGs stay as they are, transparency gets your color. Know what goes into the ZIP.
- How do I get a still JPG from an animated WebP to use as a thumbnail?The format converter never keeps animation, which is exactly what a thumbnail needs: an animated WebP comes out as a single still image, normally the first frame.
- Why do the colors look slightly different after converting an image?Embedded color profiles are not carried over, and semi-transparent edges blend with the JPEG background. The three causes and how to keep the shift small.
- I need to convert confidential client designs. Does the converter upload the files anywhere?Format conversion happens inside your browser through Canvas and no image is sent to a server; outputs carry no EXIF. How to check it yourself and what stays your job.
- After converting my photos, they lost their date taken and my gallery sorts them wrongly. Why?Format conversion redraws the image, so the capture date stored in EXIF does not travel with it and galleries sort by file date. How to keep the order.
- Should screenshots full of text and tables become JPG, WebP, or stay PNG?Sharp text on flat colors suffers under JPEG. When a screenshot should stay PNG, when high-quality WebP is a good middle ground, and when JPG is unavoidable.
- My designer asked for a transparent PNG logo. Will converting my JPG to PNG remove the white background?PNG can hold transparency, but conversion does not create it. The white background of a JPG logo stays white as PNG. What to ask your designer for instead.
- The marketplace I sell on will not accept WebP images. How do I prepare mine?If your platform's upload page lists JPG and PNG only, convert WebP images to JPEG in one batch, with white behind cut-outs and file names kept.
- I cannot insert WebP images into a Word document or PowerPoint deck. What can I do?Some Office versions and desktop programs refuse WebP. Convert graphics to PNG and photos to JPEG before inserting, or put them in a PDF directly.
- What quality should I use when converting PNG to JPEG: keep 90 or go lower?The default of 90 is safe for a one-off conversion. When to drop to 75 or 85, why there is no quality slider for PNG, and when the compressor fits better.
- To get WebP images, should I use the format converter or the image compressor?Both save WebP at a quality you choose, but the converter changes format and leaves files already in it alone, while the compressor re-encodes every image to shrink it.
- If I convert JPG to WebP and back to JPG, do I lose quality?Yes. JPEG and WebP are both lossy, and each hop between them strips new detail. How to avoid the chain by converting from the original or a PNG working copy.
- I added a JPG and chose JPEG to make it smaller. Why did the converter leave it unchanged?The format converter leaves files already in the target format alone, since re-encoding would change nothing but quality. To shrink a JPG, use the image compressor.
- The print shop refused my images because they are WebP. Which format should I convert them to?Convert designs and text-heavy artwork to PNG with no extra loss, and photos to JPEG at quality 95. Remember conversion adds no pixels, which printers care about too.
- Will converted images keep their file names so I can match them to product SKUs?Yes. The full name stays and only the last extension changes, even when the name contains dots. Plus three cases worth checking before uploading to your store.
- What is the difference between JPG and JPEG, and do I need to convert between them?None: JPG and JPEG are two extensions for the same format, so there is nothing to convert. Why two names exist, when renaming is enough, and what the tool does with each.
