How to use the Photo Enhancer

  1. 1Drop one photo or a batch.
  2. 2Pick a preset (Auto fix, Product photo, Vivid, Soft or B&W).
  3. 3Fine-tune brightness, contrast, saturation, sharpen, denoise, hue, auto levels and white balance.
  4. 4Check the before/after slider, then process.
  5. 5Download single images or the ZIP.

Product photos from a phone are usually fine in composition and poor in tone: a grey cast on the white sweep, flat contrast under shop lighting, a yellow tint from a tungsten bulb, and a little noise from a high ISO. The Photo Enhancer is the enhance product photo step that fixes those in one pass, with presets for people in a hurry and individual sliders for people who know what they want, applied consistently across a whole batch.

How it works

  1. Drop one image or a full set.
  2. Pick a preset: Auto fix (levels plus white balance), Product photo (auto levels, mild sharpening, slightly lifted whites), Vivid, Soft or B&W.
  3. Fine-tune with the sliders: brightness, contrast, saturation, sharpen, denoise, hue, plus the auto levels and white balance toggles.
  4. Drag the before/after handle on the preview to judge the change at 100%.
  5. Process the batch and download the ZIP.

Auto levels stretches the histogram so the darkest pixels become true black and the brightest become true white, which alone fixes most dull photos; it is the auto levels online step people usually reach for Photoshop to do. White balance estimates the colour cast from near-neutral pixels and removes it, turning a yellowish white background back to white. Sharpen uses an unsharp mask tuned for product edges rather than skin, so you can sharpen image online without haloes, and denoise runs before sharpening so grain is not amplified.

Why it matters

Tone problems cost sales twice: shoppers scroll past dull thumbnails, and marketplaces reject backgrounds that are not white.

  • Amazon wants a pure white background (RGB 255, 255, 255). A grey-cast photo reads as 235 to 245 on the background; auto levels and white balance push it to 255 without a cut-out.
  • Etsy recommends at least 2000 px on the shortest side, and at that size soft focus is obvious; a light sharpen restores edge definition after resizing.
  • TikTok Shop explicitly favours realistic shots over heavy filters, so the Product photo preset is deliberately restrained.
  • Consistent tone across a Shopify collection matters more than any single perfect image; applying one preset to the batch delivers that.

Tips

  • Correct white balance before anything else; every other slider behaves better once the cast is gone.
  • Keep sharpen under about 40 on a 0 to 100 scale for images that will be downsized; the marketplace resample adds its own softness that a moderate setting compensates for.
  • Use denoise only on visibly grainy photos, since it also smooths fabric texture.
  • Save contrast for the B&W preset and use auto levels for colour photos; contrast on its own clips highlights on white backgrounds.
  • Enhance first, then upscale with the Image Upscaler and compress with the Bulk Image Compressor; sharpening after compression exaggerates JPEG artefacts.
  • Enhanced cut-outs from the Background Remover look most natural with a shadow from the Drop Shadow & Reflection Adder.

Frequently asked questions

What does the Auto fix preset do?

Auto fix combines auto levels and white balance: it stretches tones so blacks are black and whites are white, and removes any colour cast measured from neutral areas. It leaves saturation and sharpness alone, which makes it a safe first step for almost any product photo.

Can I apply the same settings to many photos?

Yes. Choose a preset or dial in sliders once, drop up to 200 images and every file gets identical processing. The before/after handle helps you judge settings on one image before committing to the batch, and the ZIP download collects everything at the end.

Will it make my white background pure white?

Usually. Auto levels and white balance push a slightly grey or warm background toward RGB 255, 255, 255, which Amazon's main-image rule requires. If the background is heavily shadowed or coloured, use the Background Remover instead and check the corners with the Image Colour Picker.

Is the enhancement destructive?

The original file is never modified; a new file is created. Adjustments are applied in a fixed order (denoise, white balance, levels, colour, sharpen) to the decoded pixels and exported at the quality you choose. Keep the originals if you might want different settings later.

Should I sharpen before or after resizing?

After. Resizing softens edges, so sharpen the image at its final size. If you enhance first and then resize with another tool, keep sharpen low here, around 20 to 30, and rely on the other tool's output. Never sharpen after heavy JPEG compression, which amplifies artefacts.
