3D Rendering File Formats:
What to Request and Why It Matters

Most clients who commission architectural renders accept whatever file formats the studio delivers by default — usually JPEG files at a standard resolution. Often that's fine. But for any project where renders will be used in printed materials, adapted for multiple formats, or stored for future use, the format decision matters more than most clients realize.

This guide covers the main output image formats for architectural renders, when each is appropriate, what resolution to specify for different use cases, what source files are worth requesting, and the specific format requirements for animations. It's written from the client side — what to ask for, not what studios use internally.

Output Image Formats: The Main Options

JPEG (.jpg) is the default format for most architectural rendering deliverables. It uses lossy compression — meaning some image data is discarded to reduce file size — but at high quality settings (JPEG quality 90–100), the visual difference from lossless formats is imperceptible on screen. JPEGs are suitable for web use, email sharing, social media, and digital presentations. The key limitation is that each time you open, edit, and re-save a JPEG, additional quality is lost from the compression. For a file that will only ever be viewed (not edited), JPEG at high quality is perfectly adequate. For a file you'll need to touch in Photoshop repeatedly, choose another format.

PNG (.png) uses lossless compression — no image data is discarded — and supports transparent backgrounds. PNG is the correct format when the render needs a transparent background (no white fill behind the building, for use in Photoshop compositing) or when the file will be repeatedly opened and re-saved during post-production. PNGs are larger than JPEGs at the same resolution. For standard architectural render delivery where you won't be editing or compositing, JPEG is smaller and practically equivalent in quality.

TIFF (.tif) is lossless, supports multiple color depths (8-bit, 16-bit, 32-bit), and is the standard format for print production workflows. If renders are being handed directly to a graphic designer for brochure or large-format print production, TIFF at 300 dpi is the appropriate request. TIFF files are large — a 6000 × 4000px TIFF at 32-bit can be 100MB or more — but for print work, that data is needed. TIFF also supports LZW compression, which reduces file size without quality loss.

EXR (OpenEXR, .exr) is a high dynamic range format that stores significantly more tonal information than standard 8-bit formats. While JPEGs capture about 256 brightness levels per channel, EXR files can store thousands of levels, giving post-production artists much greater flexibility to adjust exposure, recover highlight detail, and grade color without banding or artifacts. EXR is the correct format if you anticipate significant post-production work — for example, if the studio delivers EXR files and your post-production team will do color grading or composite additional elements. For most standard deliveries where the renders are already finished and color-corrected, EXR adds file complexity without practical benefit.

Resolution: What to Specify for Different Use Cases

Resolution is the single most practical specification to get right in your brief. Here are the standard requirements by use case:

The most common client mistake is requesting renders at standard resolution and then needing them at print size — only to discover that a 1920px image printed at A1 size looks soft. Always specify the largest output size you anticipate needing, and downsize for web and digital use. You cannot increase resolution after the fact without re-rendering.

PSD Files: When to Request Layered Photoshop Files

Layered PSD files are worth requesting when you anticipate making post-production adjustments to the render — swapping sky backgrounds, adding or removing people and vehicles, adjusting material colors, or adapting the image for different crops and formats.

A well-organized PSD from a rendering studio will include separate layers for: the main render, the sky, shadows, people and entourage, text overlays if any, and adjustment layers for color and exposure. This gives your design team the ability to adapt the renders for different marketing applications without going back to the studio for a re-render.

Not all studios provide PSD files as standard — request them explicitly in your brief if you want them. Some studios charge a small additional fee for organized PSD delivery (it takes time to organize layers properly); others include it at no charge. Decide whether you need PSD files before briefing, not after delivery.

Source 3D File Formats: What Clients Need to Know

In addition to the output image files, you may want to request the source 3D model from the rendering project. This is worth doing if:

• The project will be rendered in phases and you want to ensure continuity between studios or production batches
• You anticipate needing updated renders as the design changes during construction
• The model will be used for construction visualization, BIM coordination, or virtual reality applications

Common 3D model formats include Revit (.rvt) for BIM-coordinated models, SketchUp (.skp) for design development models, 3ds Max (.max) for fully textured and lit rendering scenes, OBJ and FBX as interchange formats compatible with most 3D software, and DWG/DXF for 2D drawings in AutoCAD format. Specify which format you need based on what software your team or future studio will use. Not all formats transfer cleanly — ask the studio specifically whether the delivered model includes materials and lighting (a "scene file") or just geometry.

Animation File Formats

For architectural animations, the standard delivery formats are:

MP4 (H.264 or H.265) for standard web delivery, email, and digital presentations. H.265 (HEVC) produces better quality at smaller file sizes than H.264 but requires a more capable device to play back. Most studios deliver MP4 H.264 as standard because it plays everywhere.

MOV (ProRes) for high-quality delivery to broadcast or high-spec display environments. ProRes is much larger than H.264 but retains more color information for post-production or high-quality projection. Request ProRes if the animation will be color-graded, composited, or displayed on a professional monitor or projector.

Frame sequences (PNG or JPEG per frame) give you or your post-production team maximum flexibility for editing, color grading, and assembling the final video with custom music and titles. Request frame sequences if you want control over the final post-production pass.

For aspect ratio, the standard 16:9 (1920×1080 HD or 3840×2160 4K) is appropriate for most uses. If the animation will also be used vertically (Instagram Reels, TikTok) request a 9:16 crop at the same time as the landscape delivery — it's far easier to set up during production than to crop and re-export after the fact.

What to Include in Your Format Specification

When briefing a rendering project, include these deliverable specifications alongside your design brief:

• Format: JPEG / PNG / TIFF / EXR — specify per use case
• Resolution: Pixel dimensions, not just "high resolution" — specify the largest size you need
• Color profile: sRGB for web/screen use, Adobe RGB or CMYK-ready for print production
• PSD files: Yes or no — if yes, indicate whether you want organized layers
• Source 3D files: Whether you need the scene file, and in what format
• Animation format: MP4, MOV ProRes, or frame sequence; resolution; aspect ratio(s) needed
