Qué es PNG → JPG?
A PNG to JPG converter transforms lossless PNG images into compressed JPEG format, typically reducing file size by 60–80%. PNG files store every pixel perfectly and support transparency, but this comes at a cost — a 4000×3000 photo saved as PNG can be 15 MB, while the same image as JPG at 85% quality is around 2–3 MB with virtually no visible difference. TweakFiles converts your PNG files to JPG entirely in your browser, ensuring your images never leave your device.
Por qué convertir PNG → JPG?
PNG is overkill for photographs. The PNG format was designed for graphics with sharp edges, text overlays, and transparency — not for photos with millions of color gradients. When you save a photograph as PNG, the lossless compression barely reduces the file size. Converting to JPG applies lossy compression tuned for photographic content, discarding visual data that the human eye can't detect. The result: files that are 5–10x smaller with no perceptible quality loss. This matters for email attachments (25 MB limit on Gmail), website loading speed (Google penalizes slow pages), social media uploads, and cloud storage costs.
Ideal para:
- Photos exported from editing software in PNG format
- Screenshots that don't need transparency
- Images for email attachments under 25 MB
- Website images where loading speed matters
- Social media uploads (Instagram, Facebook, LinkedIn)
Detalles técnicos
When converting PNG to JPG, transparency is replaced with a white background. If your PNG has transparent areas, they will appear white in the JPG output. JPG does not support transparency — use WebP if you need both compression and transparency. TweakFiles uses a quality setting of 92% by default, which preserves fine details like text and edges while achieving significant compression.
