Frequently Asked Questions

Tokens & Payment

What are tokens and how do they work?

Tokens are the internal currency of the FotoLab service. 1 token = 0.01 BYN (1 Belarusian kopeck). At registration you receive 250 free tokens, refreshed every 30 days. Free tokens are spent first.

Cost depends on selected settings:

  • Color correction — 20 💎 (always included)
  • Upscale: x2 — 15 💎, x4 — 30 💎, auto — 20 💎
  • Face restoration: Fast — 10 💎, Quality — 15–25 💎 (depends on "Fidelity")
  • High precision — +5 💎 (Standard is default, free)
  • Turbo — +20% to total cost

Examples: color correction only = 20 💎; color correction + x2 + Fast face = 45 💎; maximum (color + x4 + Quality face + High precision) = 80 💎.

How to buy tokens?

The service is currently in beta testing and token purchases are temporarily unavailable. For testing, use the 250 free tokens granted at registration and refreshed every 30 days. When purchases become available, payment will be accepted in Belarusian rubles through a secure payment system with an electronic receipt.

Can tokens be refunded?

No. Under Article 736 of the Civil Code of the Republic of Belarus, refunds for properly rendered services after the start of actual performance are not provided. Once processing starts, GPU computing resources are already consumed. Subjective assessment of the result is not grounds for a refund (Article 31 of the Law of Belarus "On Consumer Protection"). Compensation is possible only for a confirmed technical failure.

File Formats

What photo formats does the service support?

FotoLab accepts all major photo and image formats:

RAW formats (unprocessed sensor data from the camera):

  • NEF — Nikon Electronic Format (Nikon)
  • CR2 — Canon Raw 2 (Canon)
  • CR3 — Canon Raw 3 (Canon, newer models)
  • ARW — Sony Alpha Raw (Sony)
  • DNG — Digital Negative (Adobe, universal RAW)
  • ORF — Olympus Raw Format (Olympus)
  • RW2 — Panasonic Raw 2 (Panasonic/Lumix)
  • RAF — Fuji Raw Format (Fujifilm)
  • PEF — Pentax Electronic Format (Pentax)
  • SRF — Sony Raw Format (Sony, older models)
  • KDC — Kodak Digital Camera (Kodak)
  • SR2 — Sony Raw 2 (Sony)
  • NRW — Nikon Raw (Nikon, COOLPIX models)
  • ERF — Epson Raw Format (Epson)
  • MEF — Mamiya Electronic Format (Mamiya)
  • 3FR — Hasselblad 3F Raw (Hasselblad)
  • DCR — Kodak CRW (Kodak)

Raster formats:

  • JPEG / JPG — the most common format, lossy compression
  • PNG — transparency support, lossless
  • WebP — modern Google format, efficient compression
  • TIFF / TIF — lossless format, used in print production
  • HEIC / HEIF — Apple format (iPhone default)
  • AVIF — next-gen format based on AV1, excellent compression
  • JXL — JPEG XL, successor to JPEG, modern format
  • BMP — uncompressed raster format (Windows)
  • GIF — format with animation support (first frame processed)
  • PPM / PGM / PBM — raw raster formats (Netpbm)

Maximum file size — 50 MB.

Processing results are always returned in high-quality JPEG. When selecting x4 upscale, a full-resolution version is available.

How to properly send RAW files?

Via the website — simply drag and drop or select the RAW file; it uploads in full without compression.

Via Telegram bot — send the RAW file as a document 📎, not as a photo. If sent as a photo, Telegram compresses it to ~1600px and converts to JPEG — all RAW advantages will be lost.

Processing Settings

Which settings should I choose to avoid wasting tokens?

Tips for saving tokens:

  • Upscale: If the photo is already large enough (side > 3000px), choose "off" or "auto" — auto enables x2 only when upscaling is really needed. x4 costs twice as much as x2 — use only for large-format printing.
  • Face restoration: Turn off on landscapes, documents and interiors — this saves 10–25 💎. Fast mode (10 💎) suits 90% of portraits. Quality (15–25 💎) makes sense only for valuable/vintage photos with heavy damage.
  • Fidelity: At 0.7 (default) Quality mode costs 20 💎. Lowering to 0.3–0.5 reduces the price to 15 💎, but the result will differ more from the original.
  • Precision: "Standard" (default, free) produces results virtually identical to "High" (+5 💎). High precision only makes sense for critical tasks with fine textures — in most cases the difference is unnoticeable.
  • Turbo: Enable only when in a hurry — otherwise the regular queue works fine.

How does face restoration work and what is "Fidelity"?

The service offers two face restoration modes:

Fast (10 💎) — automatically restores facial structure (eyes, nose, mouth). Suitable for light to moderate blur, JPEG artifacts. Fast, but with heavy damage may alter facial features.

Quality (15–25 💎) — advanced method with a "Fidelity" parameter (0.3–1.0) that controls the balance between reconstruction and preserving the original. Cost depends on the Fidelity value (lower = cheaper). Allows fine-tuning the result for valuable portraits and archival photos.

If the photo has no faces (landscape, document) — turn off face restoration to save tokens.

What is DPI and what does it affect?

DPI (dots per inch) — print resolution: how many dots per inch will be specified in the file metadata. Does not affect the number of pixels — the image size in pixels does not change. Only the label used by printing and layout programs changes.

  • 150 — for screens, web and drafts
  • 300 — standard for quality printing (photos, magazines) — recommended default
  • 600 — for fine details and large-format printing

If you don't plan to print the photo — DPI doesn't matter, leave 300.

What are "Standard" and "High" precision?

Standard (free, default) — half-precision processing. Faster, uses fewer resources. Result quality is virtually identical to "High" — the difference is impossible to notice on 99% of photos.

High (+5 💎) — full precision computation. Slower, requires more video memory. May yield slightly better results on upscale of photos with very fine textures (fabrics, leaves, fine ornament).

Recommendation: in most cases Standard precision is sufficient. High makes sense only for tasks where every detail matters at large magnification.

How long does processing take?

Regular processing takes from a few seconds to a few minutes depending on system load and selected modules. Color correction only is fastest; full set with x4 and Quality face restoration takes longer. Turbo mode processes photos out of queue — results are much faster.

Security & Rights

Are my photos safe? Who sees my photos?

Yes. All data is transmitted over an encrypted HTTPS/TLS channel. Uploaded images are processed automatically — no one views your photos manually. Originals and results are stored for no more than 24 hours and automatically deleted. Files are accessible only through your authorized access. You can delete all your data early via your account or a command in the bot.

Who owns the processed photos?

You retain all rights to uploaded and resulting images. The service does not acquire or claim rights to your content. Processing is performed automatically using proprietary software of the Provider. The composition and architecture of the algorithms used are a trade secret. The processing result belongs to you to the same extent as the original belonged to you.
