Why Choose Our Service?
72 DPI to 300+ DPI
Transform web-resolution images into print-ready assets. AI super-resolution adds real pixel density — not interpolated blur — so your 72 DPI web graphic becomes a crisp 300 DPI print file.
True Detail Reconstruction
Real-ESRGAN doesn't stretch pixels like bicubic or bilinear interpolation. It uses neural networks trained on millions of image pairs to reconstruct texture, edges, and fine detail at higher resolutions.
Retina & HiDPI Ready
Modern displays demand 2x-3x pixel density. Increase resolution to match Retina, 4K, and 5K displays so your images look tack-sharp on every screen, from iPhones to studio monitors.
Up to 4x Resolution Boost
Choose 2x for moderate resolution increase or 4x for maximum pixel density. A 1000x1000 image at 72 DPI becomes 4000x4000 — equivalent to 288 DPI at the same physical size.
Preserves Color & Tone
Resolution enhancement maintains accurate color reproduction, tonal range, and white balance. Critical for product photography, artwork reproduction, and brand assets where color fidelity matters.
Any Source Format
Upload PNG, JPG, WebP, HEIC, TIFF, or BMP. Get back a high-resolution file ready for print shops, display advertising, photo books, or digital signage — no format restrictions.

Get Started NowFrequently Asked Questions
What's the difference between DPI and PPI?
DPI (dots per inch) refers to printer output — how many ink dots a printer places per inch. PPI (pixels per inch) refers to screen display — how many pixels your screen shows per inch. When people say 'increase DPI,' they usually mean increasing the pixel count so the image can be printed at higher DPI without quality loss. Our tool increases actual pixel count (PPI), which directly enables higher DPI printing.
Can I increase resolution from 72 DPI to 300 DPI?
Yes. A 72 DPI image needs roughly 4x the pixel count to print at 300 DPI at the same physical size. Our 4x upscale mode does exactly this — a 1000x1000px web image becomes 4000x4000px, giving you approximately 300 DPI at the original print size. The AI fills in genuine detail rather than blurry interpolation.
Does increasing resolution actually add detail?
AI super-resolution adds realistic detail that traditional upscaling cannot. Real-ESRGAN is trained on millions of high/low resolution image pairs, so it learns what textures, edges, and patterns should look like at higher resolutions. The result isn't hallucinated detail — it's statistically accurate reconstruction based on the existing image content.
What resolution do I need for professional printing?
Standard offset printing requires 300 DPI. Large-format printing (banners, posters) needs 150 DPI at final size. Fine art and photo printing may require 360 DPI. Magazine covers typically need 300 DPI CMYK. Our 4x resolution boost can prepare most web images for standard print requirements.
Will my print shop accept AI-upscaled images?
Professional print shops care about final pixel dimensions and DPI — not how those pixels were created. If your upscaled file meets their resolution requirements (typically 300 DPI at print size), they'll accept it. Many of our users regularly submit AI-upscaled files to commercial printers with excellent results.
How is this different from just changing the DPI in Photoshop?
Changing DPI metadata in Photoshop without resampling doesn't add pixels — it just changes how existing pixels map to physical inches. Setting a 1000px image to 300 DPI just means it prints at 3.3 inches instead of 13.9 inches. Our tool actually adds pixels with AI, increasing the true resolution so you can print larger at the same DPI.
Is AI resolution enhancement good enough for gallery prints?
For most viewing distances, yes. Gallery prints viewed from 2+ feet away look excellent with AI-upscaled resolution. For extreme close-up fine art where viewers examine surface texture at inches away, native high-resolution capture is still preferred. For product photography, marketing materials, and decorative prints, AI enhancement is indistinguishable from native resolution.
Can I increase resolution for both photos and graphics?
Yes. AI resolution enhancement works on photographs, product images, illustrations, screenshots, and graphics. For logos and vector-style graphics that need infinite scalability, consider combining resolution enhancement with vectorization — upscale first for more detail, then convert to SVG for resolution independence.

Understanding Image Resolution
DPI — Dots Per Inch (Print)
DPI measures how many ink dots a printer places per linear inch of paper. Higher DPI means finer detail and smoother gradients in printed output. Standard commercial printing requires 300 DPI, while large-format banners can look sharp at 150 DPI because they're viewed from a distance. A 3000x3000 pixel image printed at 300 DPI produces a 10x10 inch print.
PPI — Pixels Per Inch (Screen)
PPI measures how many pixels a display renders per inch. Standard monitors show 72-96 PPI, while Apple Retina displays reach 220-460 PPI. A "Retina" image needs 2x-3x the pixels of a standard image to look sharp on high-density screens. When you increase image resolution, you're adding the pixel density these displays demand.
Resolution vs. File Size
Doubling resolution means 4x the pixels (2x width times 2x height), which roughly quadruples file size. A 1MB web image at 72 PPI becomes approximately 4MB at 144 PPI and 16MB at 288 PPI. Our AI enhancement optimizes output so files stay manageable while maximizing visual quality.
Effective Resolution
What matters isn't the DPI metadata tag — it's the total pixel count relative to the output size. A 3000px-wide image has an effective resolution of 300 DPI when printed at 10 inches, but only 150 DPI when printed at 20 inches. Our tool increases actual pixel count, giving you the flexibility to print larger at higher DPI.
Resolution Requirements by Use Case
| Use Case | Required DPI | Typical Size | Min Pixels Needed |
|---|---|---|---|
| Web & Social Media | 72 PPI | 1200x630px | ~756K pixels |
| Retina Display (2x) | 144 PPI | 2400x1260px | ~3M pixels |
| Standard Print (Brochure) | 300 DPI | 8.5 x 11 in | ~8.4M pixels |
| Magazine Cover | 300 DPI | 8.5 x 11 in | ~8.4M pixels |
| Photo Book | 300 DPI | 12 x 12 in | ~13M pixels |
| Fine Art Print | 360 DPI | 16 x 20 in | ~41.5M pixels |
| Large Format Poster | 150 DPI | 24 x 36 in | ~19.4M pixels |
| Banner / Trade Show | 100-150 DPI | 3 x 8 ft | ~12.4M pixels |
| Billboard | 15-30 DPI | 14 x 48 ft | ~1.7M pixels |
How AI Increases Resolution
Traditional Interpolation (Outdated)
Bicubic and bilinear interpolation average neighboring pixels to fill gaps when scaling up. The result is always softer than the original — like looking through frosted glass. No new information is created, so detail is permanently lost. This is what Photoshop's "Image Size" does by default, and why designers dread scaling up raster assets.
Nearest Neighbor (Worst Case)
Nearest neighbor simply duplicates pixels, creating blocky, pixelated output. While useful for pixel art that should stay crisp, it's disastrous for photos and graphics. Each doubled pixel becomes a visible square, producing the classic "zoomed in too far" look that screams low quality.
AI Super-Resolution (Our Approach)
Real-ESRGAN uses a generative adversarial network trained on millions of high-resolution / low-resolution image pairs. It learns the statistical relationship between low-res patterns and their high-res counterparts. When you increase resolution, the AI predicts what genuine detail should exist — reconstructing sharp edges, realistic textures, and natural gradients.
Why AI Results Look Native
The "adversarial" training process means one network generates detail while another judges whether it looks real. Through millions of iterations, the generator learns to produce detail indistinguishable from native high-resolution capture. The result passes both visual inspection and print production quality checks.
Best Practices for Resolution Enhancement
- Start with the highest-quality source available
- Use PNG over JPG to avoid compression artifacts
- Choose 4x for print, 2x for screen enhancement
- Enable face enhancement for portraits
- Calculate required pixels before upscaling
- Verify output against printer specifications
- Consider vectorizing logos after upscaling
- Request a printer proof before large runs
