How to Use Image Upscaler
Upload a JPG, PNG, or WebP, choose 2K or 4K, compare the AI result, and download your image.
Step 2
AI Upscale Processing
The Image Upscaler analyzes edges, faces, textures, shadows, compression artifacts, and fine details. Then it improves the image for your selected 2K or 4K target while preserving the original crop, aspect ratio, people, objects, and background.
Step 3
Preview and Download
Compare the before and after, check natural detail, and download the Image Upscaler result in PNG, JPG, or WebP. Use the larger file for printing, ecommerce, profiles, slides, or creative work.
Core Image Upscaler Capabilities
A useful Image Upscaler does more than stretch pixels. It improves resolution, sharpens recoverable detail, protects natural texture, and exports a cleaner image for real use.
AI Resolution Enlargement
ZEnhancer Image Upscaler enhances 1080P photos into 2K or 4K clarity without only stretching pixels. It keeps the same subject, crop, angle, and framing while rebuilding cleaner edges, smoother curves, and more usable detail for downloads, screenshots, product images, profile photos, and everyday pictures.
Detail Recovery for Real Photos
A good Image Upscaler should make existing detail easier to see, not replace the whole image. Improve faces, hair, fabric, product surfaces, pet fur, landscapes, and small object edges while reducing compression artifacts, soft blur, and over-sharpened halos.
Clean Exports for Print and Web
Prepare larger, cleaner images for print layouts, online stores, social posts, wallpapers, portfolios, presentations, and profile pictures. Export as PNG for higher quality, JPG for smaller sharing files, or WebP when you need faster web performance.

Short answers about free daily credits, 2K–4K output sizes, how faithfully details are preserved, batch limits, and how your images are handled before you upload.
Yes. Upload your photo, then sign in to process it. Verified accounts can check in for rewards starting at 3 credits. 2K uses 5 credits per image and 4K uses 8. You need enough credits from your account, rewards, a credit pack, or a plan. Downloads have no watermark. A human-verification check may be required.
You can upload small JPG, PNG, and WebP images up to 10 MB each; they do not need to start at 1080p. Each edge must be at most 16,384 pixels, with no more than 67,108,864 total pixels. Your accepted original file is uploaded for AI processing. Severe blur, heavy compression, and missing details limit what can be recovered. Compare the result with your original before downloading.
AI enhancement can alter facial details or smooth skin, especially in very small or blurry portraits. Compare the eyes, mouth, hairline, and skin texture at 100% zoom, and keep your original. Choose the result that preserves the person's likeness; a sharper-looking face is not always a more accurate one.
You can upload these images, but AI may change small letters, numbers, logos, or packaging details. Check important characters and product details against the original before publishing. If exact lettering matters, use the original artwork or rebuild the text instead of relying on AI to reconstruct it.
2K exports have a long edge of 2,048 pixels; 4K exports have a long edge of 3,840 pixels. Both preserve the original aspect ratio and request the matching 2K or 4K AI generation tier before resizing for download. Output dimensions do not guarantee recovered detail; results depend on the source image.
You can prepare a larger image file, but print quality depends on the original photo, final crop, print size, and viewing distance. For example, a 20 × 30 inch print at 300 PPI needs 6,000 × 9,000 pixels after cropping. Ask your print lab which resolution it needs and order a small proof before committing to the full-size print.
Yes. Pro and Ultra accounts support up to 10 images per batch. Each image uses 5 credits at 2K or 8 credits at 4K, so 10 images cost 50 or 80 credits respectively. Larger selections must be split into separate batches. Check a sample before processing the rest.
Your image is uploaded for online AI processing; the upscaler does not run entirely on your device. Review the Privacy Policy and contact support if you need image-retention or model-training terms confirmed before uploading.
