Question 1

Is BlowUpImage really free?

Accepted Answer

Yes. Every core tool is free and exports have no watermark: tone and color adjustments including Dehaze, Curves, 8-channel HSL, Color Replace, film filters, .cube LUT and Lightroom .xmp import, AI background removal, crop, text, batch export, share links and the Preset Marketplace. Free accounts keep up to 10 cloud projects.

Question 2

Are exports watermarked?

Accepted Answer

No. Every export, batch ZIP and share-page download is full resolution and watermark-free on every plan. You can still add your own text or logo watermark if you want one.

Question 3

What does Pro add?

Accepted Answer

Pro ($10 per month, $49 for 6 months or $99 per year, paid once per period with no auto-renewal) adds local masks (radial, linear and brush), AI Style Transfer and unlimited cloud projects.

Question 4

Does BlowUpImage upload my photos?

Accepted Answer

No. All editing happens locally in your browser using HTML5 Canvas and WebAssembly. Your original image only leaves your device if you choose to save the project to the cloud.

Question 5

How do I remove haze or fog from a photo?

Accepted Answer

Open the editor, load your photo, go to Adjust and drag Dehaze to the right to restore contrast and color. Negative values add a soft mist instead. With Pro you can dehaze just one area using a local mask.

Question 6

How do I change the color of an object in a photo?

Accepted Answer

Open Color Replace, click Add color and click the object with the eyedropper. Pick the new color, then fine-tune the Hue, Saturation and Luminance ranges, Edge softness and Strength. Keep Preserve brightness on for natural shading.

Question 7

How do I remove a background for free?

Accepted Answer

Choose Background and click Remove background. The AI cuts out the subject on your device. Refine the edges with Erase and Brush, then export a transparent PNG or add a color, gradient or image backdrop.

Question 8

Do I need to install anything?

Accepted Answer

No installation is needed. BlowUpImage runs entirely in a modern browser on desktop, tablet or phone.

Question 9

Can clients see my edits without signing up?

Accepted Answer

Yes. Turn on Share for any saved project to get a public link. Anyone can view it and download the preview for free, without an account.
