AI Image Enhancement
Upscale, sharpen, restore, and refine any image with AI. WaveSpeed's image enhancement tools turn low-quality inputs into high-resolution, production-ready outputs — via API, web, or free on your desktop.
Every Enhancement Tool, One Platform
WaveSpeed gives you a complete suite of AI image enhancement tools — from resolution upscaling to face restoration to background cleanup. Use them in the cloud or run them locally for free.
| Tool | What It Does | Available On |
|---|---|---|
| Image Upscaling (2x–4x) | Increase resolution while recovering sharp detail — turn a 512px thumbnail into a crisp 2048px image. | Cloud API + Desktop (free) |
| Face Enhancement | Restore and sharpen facial detail in portraits — fix blur, compression artifacts, and low-light degradation. | Desktop (free, GFPGAN v1.4) |
| Background Removal | Isolate subjects with a clean alpha mask — one click, no manual masking. | Desktop (free) |
| Object Removal / Inpainting | Erase unwanted elements from an image and fill the area seamlessly with AI. | Desktop (free, LaMa) |
| Segment Anything | Interactive object segmentation with point prompts — select any object in an image with precision. | Desktop (free, SlimSAM) |
| Noise Reduction | Remove grain and compression artifacts while preserving texture and edge detail. | Cloud API (via upscaling models) |
Three ways to enhance
Choose the workflow that fits your project — from quick one-off fixes to massive batch pipelines.
| Path | Best For |
|---|---|
| Web Playground | Quick one-off enhancements — upload, enhance, download. |
| REST API | Production pipelines — batch-enhance thousands of images programmatically. |
| Desktop App (free) | Private, local processing — no uploads, no API key, no cost. |
AI Image Enhancement — Before & After
Real enhancement results across different use cases — all processed on WaveSpeed.
⬆️ Upscaling
| Before | After | Notes |
|---|---|---|
| E-commerce product thumbnail, 256px, soft edges | Sharp 1024px image with recovered fabric texture and color accuracy | 4x upscale — ready for product detail pages and print |
| Old family photo, 400px, faded and slightly blurry | 1600px output with recovered facial features, natural skin tones, and cleaned-up background | Combines upscaling + denoising in a single pass |
👤 Face Enhancement
| Before | After | Notes |
|---|---|---|
| Group photo from a compressed WhatsApp forward — faces pixelated | Every face sharpened with natural detail — pores, eyebrows, and expressions recovered | GFPGAN processes each detected face individually |
| Low-light selfie with motion blur | Clear portrait with sharp eyes, smooth skin tone, and reduced noise | Enhancement without over-smoothing — preserves natural texture |
✂️ Background & Object Removal
| Before | After | Notes |
|---|---|---|
| Product photo with a cluttered kitchen background | Clean isolated product on transparent background — ready for any backdrop | One-click removal, no manual masking required |
| Landscape photo with a power line cutting across the sky | Same scene with power line erased and sky seamlessly filled | LaMa inpainting handles complex textures like clouds and gradients |
🎯 Segment Anything
| Before | After | Notes |
|---|---|---|
| Complex scene with multiple overlapping objects | Precise mask of a single selected object — click to select, export the mask | SlimSAM handles occlusion and fine edges like hair and foliage |

Q & A
What is AI image enhancement?
AI image enhancement uses artificial intelligence to improve image quality — increasing resolution, sharpening detail, restoring faces, removing backgrounds, erasing objects, and reducing noise. WaveSpeed provides all of these through a web playground, REST API, and free desktop app.
Which enhancement tools are free?
Image Upscaler (ESRGAN), Face Enhancer (GFPGAN v1.4), Background Remover, Object Eraser (LaMa), and Segment Anything (SlimSAM) are all free in the WaveSpeed Desktop app. They run locally on your GPU — no uploads, no API key, no watermarks, no subscription.
What's the maximum upscale factor?
WaveSpeed supports 2x to 4x upscaling depending on the model. ESRGAN in the Desktop app offers slim, medium, and thick quality options for different speed-quality trade-offs. Cloud-based upscaling models support similar ranges with higher throughput for batch jobs.
Can I batch-enhance images via API?
Yes. WaveSpeed's REST API supports batch processing for all cloud-based enhancement tools. Submit multiple images in a single request, then retrieve results via webhook or polling. Official Python and JavaScript SDKs are provided.
How much does it cost?
Desktop tools are completely free — forever, with no limits. Cloud-based enhancement via API uses usage-based credits, with cost varying by tool and output resolution. Credits are valid for 365 days. Visit the Pricing page for current rates.
