Is it free to convert images on PDFFlare?

Yes, converting images on PDFFlare is 100% free. No signup, no watermarks, no hidden fees.

Is my image data safe when converting?

Absolutely. PDFFlare processes your images entirely in your browser using the Canvas API — they never leave your device.

What formats can I convert between?

You can convert between JPG/JPEG, PNG, and WebP formats. Upload any of these formats and choose a different one as the output.

Will converting change the image quality?

Converting to JPG or WebP uses lossy compression, which may slightly reduce quality. Converting to PNG is lossless and preserves full quality.

When should I use PNG vs JPG vs WebP?

Use PNG for images with transparency or when you need lossless quality. Use JPG for photographs and general web images. Use WebP for the best compression with good quality — ideal for modern web use.

Does converting to PNG support transparency?

Yes. If your source image has transparency (like a PNG or WebP with alpha), converting to PNG will preserve it. Converting to JPG will fill transparent areas with white.

Do I need to install any software to convert images?

No. PDFFlare runs entirely in your browser — there is nothing to download or install. It works on any device with a modern web browser, including Chrome, Safari, Firefox, and Edge.

Can I convert images on my phone?

Yes. PDFFlare is fully responsive and works on iOS and Android devices. Open the tool in your mobile browser, upload a photo, choose the output format, and download the converted image.

Which format produces the smallest file size?

WebP typically produces the smallest files — roughly 30% smaller than JPG at the same visual quality. JPG comes second, and PNG produces the largest files because it uses lossless compression that preserves every pixel.

Can I convert HEIC/HEIF images?

PDFFlare currently supports JPG, PNG, and WebP as input formats. HEIC images from iPhones are not yet supported directly. As a workaround, open the HEIC file in your Photos app and save it as JPG first, then upload it here.

When Do You Need to Convert an Image?

Making WebP files compatible with older software. WebP is great for the web, but some desktop applications, printers, and older browsers don't support it. Convert WebP to JPG or PNG so the image opens everywhere without issues.

Shrinking PNG screenshots to JPG. Screenshots saved as PNG can be several megabytes. Converting to JPG dramatically reduces file size with minimal quality loss — ideal for sharing in emails, Slack, or documentation.

Adding transparency by converting to PNG. JPG does not support transparent backgrounds. If you need a logo or graphic with transparency, convert it to PNG and remove the background in your editing software.

Preparing images for specific platforms. Some upload forms only accept certain formats. E-commerce sites may require JPG product photos, while design tools may need PNG. Convert once and upload without errors.
