💡 Tip of the Day
Resize images for faster loading times.
This image converter handles PNG, JPG, and WEBP with simple controls for quality and size. Drag in a few files, pick your output, and click convert. You get quick previews, clear filenames, and download links for each image. Everything runs locally, so your files stay on your device.
Image converter - quick start
- Add images by dropping them into the box or clicking browse.
- Select output - PNG, JPG, or WEBP - and set quality if needed.
- Turn on resize if you want new dimensions and keep aspect checked for safe scaling.
- Pick a background color for JPG so transparent areas do not turn black.
- Click convert and download the files, or use Download All to save them in one go.
Convert PNG to JPG - quality and color basics
JPG does not support transparency, so a background color is applied behind transparent pixels. White is fine for most use cases, but brand palettes sometimes call for a light gray or off white. If your images include text or crisp UI edges, use a higher quality setting and consider PNG instead to avoid visible artifacts.
WEBP converter - when to use it
WEBP often gives smaller files at similar visual quality compared to JPG and PNG. It is a solid choice for product galleries, blogs, and documentation images where size matters. Some browsers on older systems still lack full WEBP support, but most modern browsers handle it well. If a user’s browser does not support WEBP, this tool falls back to PNG during export to keep the workflow smooth.
Batch image conversion and resize images - a simple workflow
Set your preferred format, turn on resize, and process a full set in seconds. If you only set the width or only set the height with Keep aspect on, the tool calculates the other side automatically. When both width and height are set with Keep aspect on, the image is scaled to fit within that box. This keeps product grids and blog thumbnails tidy without distortion.
Comparison - manual export vs image converter
| Aspect | Manual export in desktop app | Image converter in browser |
|---|---|---|
| Setup time | Open, import, set options each time | Drop files, pick format, convert |
| Batch handling | Click heavy across many images | Convert and download all at once |
| Resize control | Manual presets or actions | Width or height with keep aspect |
| Transparency handling | Custom background per export | One background color for JPG |
| Cost and install | License or app install needed | Free and browser based |
Bullet notes - tips for clean results
- For crisp UI screenshots, PNG stays sharp at small sizes.
- For photos, JPG or WEBP with 0.82 to 0.92 quality looks natural.
- When shrinking images, reduce in one step instead of several passes.
- Keep filenames predictable - add a suffix so versions are easy to track.
Real story - saving a product launch from bloat
A friend who runs a small shop had 60 lifestyle photos that were 5 to 12 MB each. The first draft of their landing page crawled because the gallery loaded the original files. We converted everything to WEBP at 0.86 quality and resized the longest side to 1600 px. The page felt snappy, image clarity held up, and the bundle dropped to under 20 MB total. The only change was format and size - no design tweaks needed.
How this works - under the hood in plain terms
The converter draws your image onto a hidden canvas, then exports it as PNG, JPG, or WEBP. Quality is applied during export for JPG and WEBP. If you want to read more on the canvas approach, the MDN docs are clear and practical MDN toBlob.

Two quick questions before you export
- Will this image ever need a transparent background - if yes, pick PNG or WEBP instead of JPG.
- What is the largest size it will display on your site - match your resize to that number so you avoid shipping pixels no one will see.
Use this image converter as a fast step between raw assets and your CMS. Keep the process simple - choose the smallest format that still looks right, resize to the largest display size, and name files clearly. The small decisions here add up to faster pages and easier asset management.
