What is photo resolution?
The number of pixels in your photograph is known as photo resolution. More detail is equal to more pixels. Higher resolution preserves small text, hair strands, and sharp edges when printing or cropping.
Why resolution drops (and how AI fixes it)
Common causes:
Apps for messaging reduce the quality of screenshots and compress photographs.
Noise is increased by poor lighting; faces are blurred in zoom photos.
The cameras on older phones record fewer pixels.
How AI helps:
Denoising eliminates grain while preserving edges; upscaling adds pixels based on learnt patterns rather than hunches.
Deblur improves focus mistakes and motion blur.
Eyes, teeth, lashes, and skin texture are all restored with face restoration.

For people shots, activate Face Restore.
The preview was 100% zoomed in. Examine the margins, lettering, and hairlines.
Download as JPG for small files or PNG for editing.
Best settings for different photo types
Portraits and selfies
- Scale: 2x
- Face Restore: On
- Denoise: Low–Medium
- Sharpen: Low
- Tip: Watch the eyes and mouth at 100%. If skin looks plasticky, lower Denoise.
Product photos
- Scale: 2x or 4x if you need tight crops
- Denoise: Low
- Sharpen: Medium
- Tip: Zoom into edges and reflective areas. Avoid halos by reducing Sharpen one notch.
Old scans and family photos
- Scale: 2x
- Denoise: Medium
- Deblur: On (if available)
- Tip: Keep grain if it’s part of the film look. Don’t remove all noise.
Screenshots and text
- Scale: 2x or 4x
- Denoise: Off (or Low)
- Sharpen: Low–Medium
- Tip: Check small fonts. If letters look harsh, reduce Sharpen.
Is a photo enhancer free version good enough?
Yes, provided you select the appropriate tool. The free picture enhancer from Pixelfox.ai works well with most photos. You receive output in full resolution without watermarks. Pro tiers save time with batch and larger limitations for bulk tasks.
When to use 2x vs 4x upscaling
Use 2x for small printing, the web, and social media. maintains crisp, credible edges.
For tight crops, small originals, or A3/A2 prints, use 4x. If necessary, dial back sharpening and check for small artifacts.
What makes a great image enhancer?
- Recovering details: fine lines, cloth weave, hair, and pores
- Edge control: Halos-free, crisp lines
- Color fidelity: No strange changes in tone
- Natural faces: No "AI eyes" or fake skin—speed and privacy: Quick outcomes with safe handling
- Sincere sneak peeks: When you export, you get what you see.
Real results you can expect
Based on my tests on more than 200 photos:
Face Restore's 2x upscaling preserves lashes and pores in phone selfies, preventing a waxy shine.
Night photos: Streetlight glow is retained but color speckle is eliminated using medium denoise.
Product macro: When sharpening remains at Low to Medium, edge halos disappear.
Old scans: Deblur + 2x makes small print readable without flattening the roughness.
Make photo smile or sharpen it? Combine tools smartly
Pixelfox.ai also offers a smile filter and smile editor. You can make photo smile first, then enhance resolution. Do the smile edit before upscaling. This keeps edges clean and avoids double processing.
Workflow:
- Apply smile filter for a natural grin
- Export
- Re-upload to photo enhancer
- Upscale 2x or 4x with face restore for a sharp, happy portrait
Common mistakes (and easy fixes)
Excessive sharpening results in halos. Reduce Sharpen to Low to fix it.
The process of heavy denoising produces wax skin. Use only Low-Medium to fix.
Ignoring the preview Always check the edges, hair, and eyes at 100%.
Incorrect file format: Export JPG for sharing and PNG for editing.
Excessive upscaling: Reduce to 4x and crop if 8x appears phony.
How to keep file size manageable
- After upscaling, export as JPG at 80–90% quality for web
- Use PNG only if you need transparency or want to re-edit
- Resize to the exact pixel size you need for your site or print lab
When not to enhance
- Super blurry originals with no face detail at all
- Photos that are already over-processed
- Images where grain is part of the mood (leave some noise)
