01 · COMPARISON
JPG vs PNG
The two formats optimize different things. Compare the real trade-offs before converting.
| Criterio | JPG | PNG | Ventaja |
|---|---|---|---|
| Image model | Raster pixels optimized for continuous-tone imagery. | Lossless raster pixel grid. | |
| Scaling | Fixed pixel dimensions; enlarging beyond source resolution loses sharpness. | Fixed pixel dimensions; requires enough source resolution. | |
| Compression | Lossy photographic compression with adjustable quality. | Lossless compression; no JPEG-style quality slider. | |
| Transparency | No alpha transparency in standard JPEG. | Full alpha transparency. | |
| Best use | Photographs and other continuous-tone images where file size matters. | Screenshots, UI assets, pixel art and transparent raster graphics. | |
| Compatibility | Extremely broad support across browsers, apps and devices. | Universal image support. |

Use JPG for photographs
JPG is designed for efficient photographic compression. PNG prioritizes lossless pixel data and transparency.
JPG usually produces much smaller files for photos and other continuous-tone images. Its compression is lossy, so aggressive settings can introduce visible artifacts.

03 · FORMAT GUIDE
Use PNG for transparency and crisp graphics
PNG preserves pixels losslessly and supports alpha transparency, which makes it useful for UI assets, screenshots and graphics with sharp edges.

04 · FORMAT GUIDE
Compression behaves differently
Lowering JPG quality trades visual detail for file size. PNG compression does not use a quality slider in the same way; optimizers instead work on encoding and palette choices.

Convert only when the use case changes
Changing extensions does not improve an image by itself. Convert when you need a capability such as transparency, compatibility or a smaller photographic file.
06 · REAL-WORLD USE CASES

07 · RECOMMENDED WORKFLOW
Recommended workflow
Protect the best source, then export deliberately for the destination.
1. Identify the source
Decide whether the original is fundamentally vector or raster.
2. Keep the best master
Keep the highest-quality editable source before creating derivatives.
3. Optimize before delivery
Remove unnecessary metadata, dimensions or structural complexity.
4. Export for the destination
Create the format and size the receiving platform actually needs.
5. Verify in context
Check sharpness, transparency, weight and appearance at real display size.
08 · COMMON MISTAKES
Common mistakes
01
Changing the extension and expecting quality to improve.
02
Discarding the editable master after export.
03
Assuming one format is always smaller.
04
Using oversized raster assets everywhere.
05
Ignoring transparency or platform constraints.
