How to Use Videify

Drag and drop your videos onto the upload area, or click it to pick files. You can add up to 10 videos at once - MP4, MOV, WebM, MKV and AVI are supported.

Choose your output format, resolution and quality, then hit Process. Each result appears with original/result previews. Download videos individually or download all results together.

Need a specific filename? Use the File Name options to add a custom prefix, suffix, or auto-number your videos.

Use Cases, Best Settings & Common Mistakes

Use cases: compress demo reels for sharing, optimize course uploads, and batch-convert clips for social platforms.

Best settings: start with MP4 at 75-85 quality, keep original resolution when possible, and downscale only large files.

Common mistakes: over-compressing below 60 quality, converting everything to one format blindly, and forgetting metadata stripping.

Frequently asked questions

Why Local Processing Matters
Most online video tools upload your files to remote servers for processing. Videify works locally in your browser, so your videos are never uploaded, stored, or viewed by us.
Lossy vs. Lossless Compression
Lossy compression (used by JPEG and WebP) discards some image data permanently. At high quality settings the difference is invisible; at lower settings you trade some detail for a dramatically smaller file.

Lossless compression (PNG, GIF) reduces size without losing any data - every pixel in the output is identical to the original. This is ideal for logos, icons and images with sharp text.
Which format should I choose?
JPG - best for photos. Great compression at 70-85% quality with nearly imperceptible loss. Avoid for images with transparency.

PNG - best for graphics, screenshots and images requiring transparency. Larger files, but perfectly sharp.

WebP - Google's modern format. Offers better compression than JPG and PNG with support for transparency. Supported by all modern browsers.

GIF - limited to 256 colors. Legacy format mostly used for simple animations.
What is EXIF metadata?
EXIF data is hidden information embedded in image files by cameras and smartphones: GPS coordinates, device model, lens settings, timestamps and more. When you share photos online this data travels with the image. Videify's Remove metadata option strips all EXIF data, protecting your privacy with zero quality loss.
What quality setting should I use?
For web images 75-85% quality is the sweet spot - visually identical to the original but 40-70% smaller. For print or archival purposes use 90-95%. Going below 60% produces visible artifacts and is rarely worth it.
Can I compress videos without losing quality?
Yes. Use PNG or GIF with lossless workflows when quality must stay exact. If you use JPG or WebP, higher quality values reduce visible loss while still shrinking file size.
How much can image compression reduce file size?
Typical savings are around 30% to 80%, depending on the source image, selected format, target quality, and resize settings.
Is Videify free and private?
Yes. Videify is free to use and processes files locally in your browser. No account is required and your videos are not uploaded to a server.
What is the best format for website performance?
WebP is usually the best balance for web performance and quality. JPG remains a safe choice for photos, while PNG is best for graphics and transparency when quality is critical.
Can I resize and rename images in bulk?
Yes. Videify supports batch resize, conversion, compression, and custom naming with prefix, suffix, and auto-numbering.
