About photography & video tools
Photography and video creation involve managing light, dimensions, and file properties to achieve desired visual results. Tools in this category address common challenges such as calculating exposure settings, determining field of view, resizing content for specific platforms, and converting between file formats. Whether you are framing a shot, preparing images for social media, or ensuring technical specifications meet project requirements, these free online resources simplify the mathematical and technical aspects of visual media production.
Before selecting a tool, it helps to understand the core concepts each calculator or converter addresses. Aspect ratio tools maintain proportional dimensions across different formats, while exposure and depth-of-field calculators rely on the relationship between aperture, shutter speed, and ISO. File-size and bitrate calculators require knowledge of your target resolution, frame rate, and compression settings. Misunderstanding these variables can lead to incorrect results, so it is important to input accurate camera specifications, lens measurements, and desired output parameters.
The tools listed span from specialized photography calculators to general video conversion utilities. Photography-focused tools help with lens calculations, depth of field, and framing, while video-oriented tools assist with compression, format conversion, and editing basics. Many overlap in function—such as multiple aspect ratio calculators for different standard formats—so choosing the right one depends on whether you need a quick mathematical result or a full file conversion workflow.

Photography & Video tools by task
Composition & Aspect Ratios
Aspect ratio calculators help you maintain proportional dimensions when resizing images or videos for different platforms, ensuring that content does not appear stretched or cropped unexpectedly. This group includes calculators for standard formats such as 4:3, 16:9, and 16:10, as well as tools that convert between pixel ratios and CSS-compatible values. Use these when preparing files for print, web, or social media where specific aspect ratios are required.
Exposure & Focus Calculations
Exposure and focus calculators determine the technical settings needed to achieve a specific photographic result. The exposure calculator uses aperture, shutter speed, and ISO to find an equivalent exposure value, while depth-of-field and hyperfocal distance calculators help you determine how much of a scene will be in focus based on lens focal length, aperture, and subject distance. These tools are essential for planning shots in manual mode or when working with unfamiliar camera systems.
Video Conversion & Editing
Video conversion and editing tools allow you to change file formats, trim clips, adjust dimensions, and apply basic filters without installing software. This group includes converters for common formats such as MP4, MOV, AVI, and WebM, as well as utilities for resizing, rotating, cropping, and reversing video playback. These are useful when you need to prepare footage for a specific platform, reduce file size, or perform simple edits quickly.
File Size & Bitrate Planning
File size and bitrate calculators help you estimate the storage requirements and streaming quality of your images and videos. By inputting resolution, frame rate, bit depth, and compression settings, you can predict file sizes before recording or sharing. This group also includes tools for calculating ground sample distance for aerial imagery and pixels per inch for screen display, which are valuable for planning large-scale projects or ensuring compatibility across devices.
Output & Sharing Tools
Output and sharing tools convert or generate media files for specific uses, such as creating animated GIFs, capturing still frames from video, or adding subtitles and captions. This group includes the video-to-GIF converters, timecode and frame number converters, and subtitle timestamp adjusters that help synchronize text with footage. These utilities are ideal for preparing content for social media, presentations, or archival purposes.
Questions
Photography & Video FAQ
- How do I choose between different aspect ratio calculators?
- Select the calculator that matches your target format; for example, use the 16:9 calculator for widescreen video or the 4:3 calculator for standard displays. If you are resizing for a specific platform like Instagram or YouTube, check their recommended aspect ratios first, then input your original dimensions to find the correct output size.
- What information do I need to use an exposure calculator?
- You need to provide the current aperture value, shutter speed, and ISO sensitivity. If you are changing one setting—such as widening the aperture—you can input the new value and the calculator will suggest the equivalent shutter speed or ISO to maintain the same exposure level.
- Can a depth-of-field calculator tell me what lens to buy?
- No, it calculates the depth of field for a given lens and camera setup based on focal length, aperture, and subject distance. To decide on a lens, you would need to consider your photographic goals, such as portrait versus landscape work, and test how different focal lengths affect your composition.
- How accurate are video file size estimators?
- Video file size calculators provide estimates based on resolution, frame rate, duration, and compression format. Actual file size may vary depending on the specific codec, bitrate settings, and motion complexity within the video. Use the result as a planning guide rather than an exact measurement.
- What is the difference between a video converter and a video compressor?
- A video converter changes the file format—such as from MOV to MP4—while preserving the original quality settings. A video compressor reduces the file size by adjusting bitrate, resolution, or encoding settings, which may result in some loss of visual quality. Use a converter when you need a specific format, and use a compressor when file size is the primary concern.
- How can I convert a GIF to MP4 without losing quality?
- Converting a GIF to MP4 typically involves re-encoding the animation into a video format, which may change the color palette and frame rate. To preserve as much of the original look as possible, choose output settings that match the GIF's original resolution and frame rate, and select a high-quality preset if available.
